Thanks a lot for the detailed information. I am able to encode vob files
now. But I have a small problem. In the video files that I have encoded,
video and audio are out of sync. The command I used is given below:

cat *.vob | mencoder -o title2.avi -oac mp3lame -ovc xvid -xvidencopts
bitrate=840:pass=1:me_quality=6 -vop scale=640:360 -sws 2 -

Please tell what should I do, to the get the audio-video sync.
