Why not convert from the original to the pocket PC version? As you've got the original DVD that you're converting to make the xvid for your PC, why not also while you've got the VOB files ripped to your hard drive convert straight from them to the pocket pc version? VirtualDubMPEG2 or VirtualDubMod can both open the vob file directly, and if you get AC3dec (I think it's called) - an open source AC3 decoder wrapped in an ACM layer - virtualdub can also decode the audio for you.

For reference, these are the settings I use (although they're set more to get the file on my SD card rather than for best quality, I've not done full experimentation):

Resolution: 320x240 (or nearest multiple of 16 in the height if it's not 4:3 aspect ratio)
Frame rate: 25fps (mostly my DVDs are PAL)
Compression:
- Audio - 96kbps stereo MP3 for "good quality" sources - e.g. episodes of 24, 48kbps for older TV episodes that have pretty nondescript sound quality anyway
- Video - 265kbps CBR one-pass for better quality (looks pretty much perfect mostly on the axim), 205kbps for older crappier quality sources with less movement etc.

These settings give files of around 120MB per 45 minutes - so for films you might want to knock the video bitrate down slightly and maybe the audio bitrate too in order to get a film on a 256MB card.

Hope all that rambling helps some :)
