I use ffmpeg for the encoding. [If you're on Ubuntu, use the Medibuntu repository for additional codecs].
vcodec is H264 acodec is AAC here's the command line: ffmpeg -y -threads 4 -i 'input.vob' -s 320x240 -r 29.97 -vcodec h264 -g 300 -aspect 320:240 -qmin 27 -b 400 -level 13 -loop 1 -sc_threshold 40 -partp4x4 1 -refs 3 -qmax 51 -maxrate 700 -async 50 -acodec aac -ar 44100 -ac 2 -ab 128 out.mp4 that commandline is from iSquint (a mac app that uses ffmpeg) so that the resulting video can be compatible with iPods. but of course you can tweak the video bitrate, q, audio bitrate, etc. Plays cool on our CRT monitor. i also use this to convert dvd movies to fit my cellphone. however, I need to change video codec to MPEG4 to be able to play it on my SonyEricsson K530i.
