I want to know what is the best format to convert videos for ppc so i can get best combination of quality and performance, size dosnt matter for me.
I am alao looking for the best practice guide.... so i can learn how to get smooth video playback.
H.264. Read my H.264 Bible, it exaplains everything.
Thanks I am looking for your bible.
I think I may have overlooked something obvious, but where is your bible?
I'm having terrible trouble getting decent video playback on my i-mate 9502
Here guys

It seems you can't expect much from the 9502 - it doesn't have working drivers either - see http://forum.xda-developers.com/showthread.php?t=351788&page=8
You could give CorePlayer a try, though
I still have a problem that I have a wmv which play smoothly on my pc but now I convert it to h.264 but it still lagy (as before) on my wizard.
Do you use CorePlayer?
Did you try optimizing (bo Cabac etc?)
I am using core player latest build but I dont know about "optimizing (bo Cabac etc?)"
Can you explain me?
btw I convert the video from xilisoft in 320 res

I've explained this all in the H.264 Bible... there're a lot of areas of optimization.
BTW, the Wizard is VERY slow. Therefore, I recommend not only goig for CorePlayer, but also sticking to DivX if the increased storage requirements aren't a problem.
you mean divx codec, not player right?

Both. You need to encode your stuff with DivX and play back preferably with TCPMP or, even better, CorePlayer.
I switched my 9502's coreplayer setings to RawFramebuffer and now it plays QVGA video at an acceptable 24fps / 500kbps no problem. Still seems to hate VGA video though, but I guess that's a non-issue until they bring out the SDHC patch.

any other core player video settings for better performance?
The H.264 codec is not a good choice for playback on slower devices. If you flip though the h.264 bible (linked below) you'll see that even a 330 MHz OMAP (N95) isn't able to handle a h.264 video 100% without disabling features. You haven't got a chance with a 200 MHz OMAP and your going to have high CPU utilization with a 400 MHz CPU.
http://www.aximsite.com/boards/applications/222389-h-264-k-mpeg-4-part-10-avc-bible.html
If size is not a factor, then you're not gaining anything by using h.264. The main benefit of h.264 over XviD is better quality at the same size or same quality at a lower size. XviD/DivX has much lower compression complexity and requires less CPU power/utilization to decode but ends up taking more space.
If you have a fast processor and you want the best quality at the smallest size, go with h.264/AVC. If size is not a factor, stick with XviD/DivX(ASP). Even with a fast processor, you will have lower CPU utilization and longer battery life (assuming you are using CPU scaling).

unfortunately the software you refer doesnt support wmv conversion.
Well, honestly I've never needed to convert a wmv(ASF) video before. I never would have thought it would not accept WMV files, but I downloaded a music video to test and indeed, even when forced, PocketDivxEncoder wouldn't accept it. I then tried AutoGK which is another high quality converter/front end and it also would not accept WMV files (I would assume the same for Gordon Knot).
To aid you in your quest, I went on a search for tools to help you in your task.
Tools tested....
AllToAVI - http://www.videohelp.com/tools/alltoavi - easy to install, fairly intuitive, fast encoding, no option for cropping or rotation, limited audio options.
--I ran a quick test on my wmv music video using AllToAVI. The original WMV did not play very well (worse than a slide show) on my HTC Touch (Elfin - 201Mhz OMAP). The resulting XVID was actually the same size, but played perfectly.
WinFF - http://www.videohelp.com/tools/WinFF - easy to install, minimalist interface (very limited), fast encoding. Unlike AllToAVI, WinFF did not analyze the source or make suggestions on video frame rate or aspect ratio. It worked well enough and the resulting XVID looked as good and played as well as the file created by AllToAVI.
MediaCoder - http://www.videohelp.com/tools/MediaCoder - wow, this program is pretty amazing. Easy to install, tons of options, fast encoding. This program is much more customizable than PocketDivXEncoder, but this is to be expected. This program can convert from pretty much any codec to pretty much any codec. There are options for pretty much every aspect of the conversion process (which may be too much for some people). The resultant video was again the same size, but quality was a bit higher since I was able to crop the black bars.
Basically, if you can use PocketDivXEncoder (i.e. your video is supported) stick with it since it is fast, high quality and easy to use. If you want the ability to customize every single aspect of the conversion, use Media Coder. If you can't use PocketDivXEncoder and you want something very simply to convert your unsupported video, give AllToAVI a shot.
many thanks for your efforts. I am tryijgnall those convertors and will let you know the results.
can I play the 700MB dvdrip (.avi divx) version of movie on pda. Can it handle it?
Hy guys,
Just to know, I'm coming from my trusty Eten M700. I bought the HTC Touch Pro about one week ago here, in Romania.
And I must say the video playback seems way too sluggish for a phone like this. On the M700, with same coreplayer version (latest), with raw frame buffer and medium quality and no other modification I could play every video I wanted. Including 720x576 xvid clips.
On this one...no matter what I set (QTV, raw frame buffer, direct draw), everything seems a little too sluggish compared to M700.
do you have the same impression, or is it just me?
I just read another thread here about video performance but it had too much dissipated info.

Which is why it's great that you started a new thread to dissipate the info further. Read the other thread(s) again, this has already been answered and solved within coreplayer.

which topic is it? i have smilar issues
Untill now I have found that QTV with Medium acceleration, and dither on has the best performance, anyway less than m700. Setting the buffer to 8000 kb did not had any effect. Still want to hear from another pro owners what they think about this.
I agree, video playback just sucks! I hate Qualcomm processors, Xscale rulezzz!
However when I put QTv, my screen goes black and there's only sound.
How did you achieve to run it on QTv???

It depends on what kind of file you want to play with it. On mine, some 3gp and some clips compressed for mobile devices don't show anything on screen. Try to switch to raw frame buffer, and restart core player, maybe it helps?
Unfortunately the HTC Touch Pro is not the mulitmedia phone you want if your looking to run your non-mobile encoded videos. However it still can be a awesome video player if you encode videos to the right dimension and specs.
I took this past Sunday to play around with finding just the right video format and encode settings to play video as close to vga as possible. Unfortunately the Touch Pro can't play videos in full-vga resolution. HOWEVER, it can perfectly play videos in 480x320 which when you compare to a 640x480 video on the touch pro's 2.5inch screen there is no difference in quality what so ever.
When you play small videos on such a small screen you wont notice the difference in the resolution, however comparing a qvga (320x240) to the half vga 480x320 resolution you can definitely see a difference.
I use two different encoders, one being pocket divx encoder and the other videora iphone converter.
I encoded a bunch of animes and movies using pocket divx set to 480x320, 2-Pass, vhq enabled, around 850 video bitrate and 128kb stereo bitrate and all my videos look crisp on the Touch Pro and plays smoothly.
I suggest others to try it out and benchmark the playback yourself and you'll see it'll run at a easy 135%+ which is perfect for 100% smooth playback.

1.) I suggest check two things, one be sure you are running the latest build which I assume you are,
2) under preferences and under the Qtv page look to make sure "Tytn 2 driver mode" is enabled.
3) some builds have a issue of zoomed in pictures to a an extreme amount that only a black screen shows when first installed, set the zoom to 50% and then reset to the normal or best fit.
Hopefully those changes should help you out
UPDATE: Also there is one bug I know of with Coreplayer. When coreplayer is launched and left running in the back (or if still active on screen) should the device go into sleep mode and then come back you will not be able to see any video playing when choosing to start. You'll have to close coreplayer and reopen again, I noticed this the other day and just came into mind when experiencing just now again.
I almost agree with you puerrican but I think it's such a burden to reencode....I managed to get easy after I saw that everything encoded with h264, mkv and encoders like this can't be played in the pro. However, everything I had in my computer encoded in divx, xvid, normal things works just fine with the settings I put in some posts above. I just tried 700 MB DVDrip(around 1000 kbit/s and 640x272) and some videoclip(624x352 vbr around 2300kbits) both xvid and they worked ok. 688x400 AVC1 (h264) killed the pro.It's not just the resolution but also the encoder used.
EDIT: just saw the update and I wanted to mention that I'm also using the 1.2.5 build 4506 with tytn 2 mode enabled and qtv on medium selected. And touchflo3d is disabled and I'm using the spb shell (or something like that with icons on screen).
IDEA: I think it would be interesting playing back xvid 640x480 and h264 640x480 to test this idea of mine
Definitely it is pain to go and do that. Plus reencoding speed relies heavily on your pc specs, on a high end specs your looking at around 4-5 mins for a 2-pass encoded video of 24 min length. While a movie length of 90 mins or so your looking at at least 16-22 mins.
So expect much longer wait on a lower end thats not even dual core or lower clock rate.
Until pdas start sporting dedicated gpus from nvidia or other names windows mobile wont ever benefit on being a media playback alternative which is a nice plus for those not looking to carry 2-3 devices for music, pmp, pda, and phone. Wish HTC would look into intel processors for their next unit and possibly throw in a nvidia mobile gpu like the 5500 with a decent amount of video memory. I mean at this point in the technology chain its not even remotely impossible to do so... so whats the hold up with companies???
yeah, i have no problem with mp4 at 640x480 (640x360 widescreen). mkv at high res (above 640x480) is a little juttery. my movies are usually 24fps, 1000kbps, 640x360
got same settings as gigs
coreplayer is working on fix for v1.3
I'm at a lost, I tried playing 640x480 videos on my touch pro and it stutters way too much, how are you guys managing to have to it playback flawlessly?
I dont really get whats good about watching movies on a 2.5 inch screen...do you do that on such a regular basis that this is so important ?
Regarding Video, i just watch some short youtube clips and stuff like that...
Ever tried to watch a full length movie on such a small screen ? I did that on holiday on my ipod and its really hurting the eyes to concetrate on such a small screen for 90+ minutes... not really anything you want to do regularly...besides not reencoded videos take up alot of space on your memorystick...
i dont have a problem with reencoding some videos and stuff, full length movies arent meant to be watched on a phone anyway
Well, a 2,5 inch screen is a bit too small, but our Touch Pros have a 2,8 inch screen
I have a zune and it has a 3 in screen and was perfect for watching tv videos or movies, and thats half the resolution then a TP. Cant wait to get my hand on the TP !!!
To each his own, some ppl like being able to watch videos whenever the call comes. Sometimes when I have to wait for something like a class to start or I'm away from my pc, or even on a airplane or public transportation I like to be able to watch few episodes easily and clearly. A full blown movie yea its gonna be a nuisance for a long time depending on the person. But some are accustomed to it, I for one can easily watch 4-6 episodes in a row without getting any kind of headahce.
yep, its quite convient. all in one device. it has tv out as well, so since it is simalar res to tv, it looks great
music + movies on phone, no ned for mp3 player. plus i can stream movies off my pc
yeah i see that there is room for this, but i dont think many people use this so regulary that converting a few movies is that much of a pain. You will save a lot of space on your memorystick as well.
I have modifying 2 regentries and the video is now much better.
Look here:
http://forum.xda-developers.com/showthread.php?t=438318
Using CorePlayer the benchmark was before 75-95%,now 145%. on same videofile - Uncompressed VGA XviD.
Edit... I am sorry. It wasn't working. I just forgot,that I set the video quality to medium before.
You have to chose Medium Quality on Video Settings (with Qtv selected), otherwise it lags so much ..
Even on medium on motion scenses some frame drops

----- START OF THEOREY -----
If you're like me, the first thing you asked yourself after buying your Fuse was "HOLY ****! I can run 4x the storage on this thing that my old Wizard could!" Yes, 16 GB of Micro-SD goodness is freakin' sweet. But how to use it? You can only listen to so much music per week, even with Napster To Go. You can only play so many games. (I'm further reduced due to lack of a usable joy pad for Pocket Nester.) Why not throw some movies on this joker?
----- VIDEO FORMAT -----
The first thing most people want to know is "What resolution and format should I use?" I am a longtime fan of Divx. I have used it to successfully create video content for low end devices, specifically the SEGA Dreamcast. Creating or downsampling content for a mobile phone gives us a considerable edge over bigger-screen counterparts. Before we jump into the configuration of settings and knob-dicking with software, let's figure out just what kind of video we want to produce.
FRAME RATE
Most content you find will come in one of 3 frame rates:
30 FPS (VHS / NTSC Broadcast / DVD / Blu-Ray(?) )
25 FPS (PAL)
23.976 FPS (Actual frame rate used to record cinema and produce much media)
The first thing you need to realize is that many things initially encoded in 30 FPS can be converted back to 23.976 FPS with no loss of fluidity or data. If your source is a webcam, skip the scaling to 23.976 and drop down to frame decimation. If your source is film, you're in luck. The other frames are just dummy frames that waste a little data. Deleting those frames frees up more video data to better express the picture information in the other 23.976 frames. This trick allows you to:
A. Use a lower bitrate (and hence smaller file) for the same picture OR
B. Get a better picture at the current bitrate
To figure out the frame rate, load up your file in V-Dub and go to File - File Information. The Data Rate box in the Video Stream area will tell you current bit rate, while frame size will give you resolution and frame rate. If you have a 23.976 FPS source, continue. If you have a 30 FPS source that you think should be 23.976 FPS (Film, etc) :
1. Load up the file in V-Dub.
2. Go to the Video drop down menu. Select Frame Rate (CTL+R is shortcut)
3. Change the Frame Rate on the source to 23.976 FPS.
If you continue to have audio sync issues with this method, leave the file at 30 FPS and continue.
Now we are going to look at frame decimation. Frame decimation drops every X frame while keeping the audio sync'd. The end result is a file X the frame rate of the source. While this is noticeable on large screens, on the Touch Pro / Diamond Screens (and probably even the HD), it shouldn't be an issue at all. You can play with this option. It is more noticeable on film, but I cannot see a difference at all on animated sources.
I use the decimate by 2 option in VDub. Video -> Frame Rate (CTL+R shortcut) and select Decimate video frame rate by 2. Our output video is now half the frame rate of our source. The end result is we can:
A. Get a better picture with the current video bit rate OR
B. Lower the video bit rate to get the same picture in a smaller size.
I use option B. Another big advantage here is that the device is trying to decode half the frames. A general rule about audio and video playback: The lower the bit rate you ask the device to handle, the less work it has to do to decode and display the video, and less battery power will be used.
RESOLUTION
Most content you will find is around 640 x 480. DVD sources usually come around 720x480. Blu-Ray would be above that, but possibly scaled down. We are going to watch this movie on a 3 inch screen. Guess what that means? If we never found a video about 320x240, or comparable widescreen resolution, It wouldn't matter. At all. Stepping up to 640x480 is just going to quadruple the amount of pixels we are trying to express on a limited budget.
A handy tool I use in V-Dub is the 2:1 reduction filter (high quality). To kick kit on, go to Video -> Filters (CTL+F). Click add, and it should be the first filter you can choose. This cuts your resolution by half. As a rule of thumb, If I've got a source that's around 640x480 (or 16:9 equiv) or higher, I hit it with the 2:1. You'll find oddball sources like 480 x 360, you can give it a shot, but it might not be worth it. Again, lower resolution means less pixels to express both in bit rate and in reproduction (playback).
Pausing here again, tired as hell.

Smaller would be sweeter.
Taking a break for a bit, added some new material. Internets in the hotel are barely functional.
I'll be focusing on getting files down to smaller levels. The theorey should give you enough information to start dramatically cutting your file sizes. I've been moving my Boondocks DVD over to Divx 6.8 movies. Averaging 40 megs per episode.
I have been using spb mobile dvd for a few years now. It is very easy to use can convert straight from a dvd or a video file and supports vga res.
Will have to check that one out, have been thinking about backing up my DVD's to mobile, will be traveling about 26 - 30 weeks out of the year and need some boredom killers.
Gonna score some sleep and SEGA time, later all.
Added some new info, taking a pre breakfast nap.
i use slysoft clonedvdmobile. output at vga res and filesize around 700mb seems to run fine for me...although its not free, its well worth the money

This is a great bit of software. It also utilises all 4 cores on my Q6600. Another fantastic program is DvDFab which can transcode DVD to Divx/Xvid/MP4 etc on the fly, or dump the Video TS to your HD.
Going to have to check all this out. Have many a DVD that needs ripped. Wonder if any of those have a frame decimation feature. I like my 30 - 40 meg per episode cartoons.
Based on some comments in other threads, I've tried a couple of freeware programs to try to encode in the format that works so well with WMP (MP4, H.264, 640x368, 1000 Kbps, AAC @ 96Kbps): DVD Decrypter + SUPER for one and AutoMKV for the other. However, I haven't been fully successful with either, so I'm hoping that someone who uses these tools can clue me in on the appropriate settings and procedures for encoding.
The combination of DVD Decrypter and SUPER creates very nice movies for playback on the Fuze. Unfortunately, DVD Decrypter keeps the VOB structure from the DVD and SUPER follows suit, which means that a movie will be broken into several pieces at arbitrary points: unsatisfactory, to say the least. The SUPER support forum mentions a way to join inputs into a single output, but following what I understood those instructions to say did not, in fact, result in a combined file.
AutoMKV is very convenient, as it is a single program (or at least UI) to both rip and encode. Unfortunately, I haven't found the settings that generate output that is comparable to the SUPER output -- WMP won't play any of the files I've managed to create so far.
Anybody use these successfully and can share how they do it? TIA.
amerisoft, works very well for me so far, except an occasional blank screen
Just wanted to add...
I don't bother encoding video anymore. Sure, a full-blown 50 minute xvid show might be 400meg. However, the touch pro does not have any issue playing such files back.
Makes life much easier!
I'd agree. I've loaded up a couple of 700MB XVIDs and had no problem playing them.
For some reason, my Sprint Touch Pro has issues playing back even reasonable quality video. For instance, 640x480 video at 1200k (MP4) is a little choppy in WMP, and almost -everything- is extremely choppy in TCPMP, no matter how it's encoded, including 350MB 45-minute XVid TV shows.

As I understand it, it's a driver issue. (This is what I've gathered across numerous postings here; someone please correct me if I've gotten something wrong.) The Qualcomm chipset in the TP/Fuze has an efficient driver called Qtv, but Qualcomm charges for a license. WMP appears to incorporate the driver, so it's able to handle moderately challenging videos. 1200 Kbps might be a little more than it's capable of displaying smoothly, but people have reported that 1000 Kbps plays well. On my one trial with DVD Decrypter + SUPER, that was the case for me, too -- full resolution and smooth motion for a video ripped from a DVD with the specs I reported in my earlier message in this thread.
TCPMP, on the other hand, does not include the Qtv driver, so in order to get smooth playback you have to reduce the size, resolution, or frame rate.
Coreplayer has a reverse-engineered partial driver for Qtv. As a result, it falls between TCPMP and WP in capabilities. It is claimed that version 3.0 of Coreplayer will have full Qtv support.
Am I being unrealistic in my expectations WRT playback of video on the Transformer? (NB After some of the replies below, I've added this comment to emphasise my point - I am NOT talking about high-def video here [e.g. 720p], just normal PAL or NTSC video taken from standard DVDs.)
I've ripped some DVDs using Handbrake on my Mac, using the default High Profile settings. The resulting h.264 files play smoothly and nicely on the Mac.
However, on the Transformer, the playback is juddery.
These are standard-resolution DVD rips, from TV shows and movies.
I wouldn't have been surprised for HD content to be a bit dodgy, but I was surprised not to be able to play SD content smoothly.
Has anyone else got good video playback (i.e. do I have a dodgy tablet) or is the Transformer with its Tegra 2 really not up to playing full-screen SD video?
Don't use high profile. Search before you post - there is many threads about video issues of Tegra2 devices here and in Xoom forum.
Why do people keep doing this, you have a Google tablet, Google this.
The Tegra 2 has a strange limitation, it doesn't play high profile. Before you make the mistake everyone else does, high profile is not a measure of quality, its the measure of compression. The bit rate is the quality.
Put it on high profile go to advanced, turn off 8x8 transform and Weighted P Frames and Subpixel ME to 6, use MP4.
Don't bother with other peoples presets, just use Moboplayer and you will be good with this setup.
Thanks
OK, thanks to you both for sorting me out with this. I did (contrary to appearances) try to find a thread on this topic but failed. Clearly I must brush up on my searching skills.
What about YouTube playback? Even this works terrible on my transformer. It keeps droping how of frames with latest firmware update.

there will be an update for this, also the browser player works fine for me.
Settings that work
OK. After some testing with the first chapter of the Matrix DVD (because I have it to hand and it's got some nice pans and action to check the juddering against), I have found that the following settings in Handbrake give me acceptable performance on my Transformer with the h.264 codec. This is standard-definition video, please note, NOT high-def.
Note that sorting this out is far from as simple as "Google it" because there are a great many mutually contradictory sets of advice out there!
I took the Normal profile, then went to the Advanced tab and disabled CABAC and set the max B frames to 0.
This was the least dramatic setting that gave smooth playback on my Transformer. So I guess I should repeat my original question - given that my tablet appears to require much lower video settings than generally advised AFAICS in order to get smooth video playback (it's hard to measure this but this is my preception), should I worry? Or is this pretty much what everyone finds with the Transformer?
(The easiest way to get smooth video seems to be just to switch to the MPEG-4 codec and to increase the quality to about 3 to compensate. However, this gives files that are 40-50% larger, so I wanted to avoid that if possible.)
I usually use Handbrake for everything but I was in a hurry so I tried Freemake Video Converter. I converted a few downloaded x264 MMA videos. It has built in settings for Android. I was surprised how well it looked.
I'll still probably go back to Handbrake as soon as I have time to setup and test various suggested settings listed here and some other forums.

Why do people keep doing this, you have a Google tablet, Google this.
The Tegra 2 has a strange limitation, it doesn't play high profile. Before you make the mistake everyone else does, high profile is not a measure of quality, its the measure of compression. The bit rate is the quality.
Put it on high profile go to advanced, turn off 8x8 transform and Weighted P Frames and Subpixel ME to 6, use MP4.
Don't bother with other peoples presets, just use Moboplayer and you will be good with this setup.

Thanks for the info.
Are you using handbrake? If so, are you using constant quality, bitrate or target size for your encode?
The Tegra 2 supports 720p High Profile Hardware Decoding, but Honeycomb can't utilize it yet. 3.1 or something later should address this.

NOT about high-def content
Can I reiterate that my query is NOT about high-def content (e.g. 720p)? I'm talking here about being able to view simple SD content from a DVD I've bought, without juddering.
Can other folks view standard DVD rips on their Transformers using standard Handbrake settings, with no juddering during whole-screen update sections (e.g. pans or action sequences)?
I just used Adobe Media Encoder CS5 (part of the Creative Suite) to encode a file and it played flawlessly on my xformer. I used the Apple TV Preset as a base then modified the profile from main to baseline.

Could you share which modifications you made? As I don't have access to CS5, I'd need to reproduce the settings on my software.
Thanks!
there's a handbrake profile for video encoding for the transformer. search for it.
seshmaru:
Unless you know something is there then you don't know to search for it. Now I know, I have searched and found that what I posted above is basically the situation - no B frames, no CABAC.
That being said, all the discussion I have seen has been based on 720p content rather than standard def so it's not clear to a newcomer to video issues that tthe same restrictions necessarily apply.
Anyhow, that seems to be the answer so thanks to all for the help.
I have a Handbrake profile saved from back in March. I found it from a YouTube video links section, where the author of the "how-to" video about re-encoding video for the best playback on the Xoom posted a link to a pretty good Handbrake preset for the Xoom.
I am just wondering... if video playback is now better in Honeycomb 3.1, if there would be a better setting (for better quality video) out there? Does anyone have a Handbrake preset that looks really good on the Xoom that is new for the 3.1 update?
The preset I have from March works well, and videos encoded using the preset play without stutter - but the quality is a bit blurry at times... which leads me to wonder if the Xoom couldn't handle higher quality video now.
I had lots of trouble finding the right combo with Handbrake. Videos would play fine but weren't very crisp.
Switched over to the latest version of an old app - DVD Fab. Works extremely well, videos are sharp and play buttery smooth.
JFMFT,
What setting are you currently using? I'm at work so cant check mine right now. I know whatever settings I was using seemed to work pretty well-will get back to you with specifics.
If you have a solid preset to tweak, then try using the "Constant Quality" setting under the "Video" tab:
Constant Quality - Handbrake
CRF Guide - Handbrake
Read the above links; they have great info. If you don't, then at least note that higher RF means lower quality (higher compression).
For me, a single Handbrake preset doesn't produce the results I want -- good quality balanced with decent file sizes -- across different kinds of video. Animation differs greatly from fast-paced action (frames, distinct lines/edges, blur, etc.), for example.
In Handbrake, I started with H264 baseline profile settings, then settled on some tweaks in the "Advanced" tab after some reading and experimentation:
Motorola Support FAQ: Motorola XOOM - Optimal video settings
HandBrake Docs (links to option descriptions): x264 Options - Handbrake
Now, I vary only the "Constant Quality" parameter between RF 19 and 25, depending on the type and quality of the source. It takes some trial and error, but I think it's a worthwhile effort. Working first with short samples (5-10 min) from the video source will help things move quicker, too.
Get RockPlayer, it literally plays everything.
Forget Handbrake / DVD Fab. Free vs Cost issue aside, DVD Catalyst 4 FTW!
Away from home currently, but I will check into my settings & report back soon.

Hit the link above there is a section provided Handbrake info and a download link to a working preset file. =)

try this one?
Here are my Handbrake settings for my Xoom.
I'm getting pretty good results in term of quality/size.
For the Picture settings, I'm changing the Anamorphic to None and setting the Width to 1280 (be sure to check the Keep Aspect ratio).
Maybe the Anamorphic could be changed to other, I didn't test to see the difference.
You can try setting Constant Quality or increase the Bitrate value (I'm using 1500 which seems to be enough)
Encoding is quite fast (depending of the PC of course)
Enjoy playing them with the default HC video player

"video playback is now better in Honeycomb 3.1" i agree. Honeycomb 3.1 improve the hardware capabilities, so video will play more smoothly. but for video conversion, you need to increase the bit rate. this is my own experience.
