Sorry for the double post, I didn\'t realize this was two pages already.
I am stumped as to what\'s causing your problem. If you read my site, it explains where I got the cbp setting. man mplayer would give you more information.
You might try not using ogg. Instead encode the movies to divx with mp3 sound. In this way, mencoder does not have to separate the audio from the video stream. You might maintain better sync. You are probably going to need the mad library to decode this on the zaurus as fpu emulation is very slow and impractical.
