I have the following:
DVD: Audio / Video Sync is okay
VOB: vob file created on hard disk using vobcopy. File on hard disk audio / video sync is okay
MPG: used mencoder to create an mpeg file out of it, I've tried different options:
mencoder -of mpeg -mpegopts format=dvd:tsaf -oac copy -ovc copy -o outfile.mpg infile.vob
mencoder -of mpeg -mpegopts format=dvd:tsaf -oac copy -ovc copy -vf harddup -o outfile.mpg infile.vob
mencoder -forceidx -of mpeg -mpegopts format=dvd:tsaf -oac copy -ovc copy -vf harddup -o outfile.mpg infile.vob
Result is for all versions the same, the video / audio is out of sync. It looks like that the lag between audio and video is constant and doesn't increase over time (in case that matters), I would say it is about 0.5 - 1s, you clearly see people moving the mouth and then you hear what they say, so sound is behind.
Any idea?
Thanks!
