[MPlayer-users] Altivec IDCT & audio un-sync problem (ENGLISH)

Try with -delay -0.25. If it works better, then you've experienced the bug
that sits in mplayer for ages: mplayer has some serious problems with
dvd audio sync, always around this magic 0.2-0.3 sec.

Neither me nor mplayer authors know where this difference comes from.
Furthermore when you rip such DVD for example to AVI or OGM with ac3
sound, it plays perfectly well, with correctly synced audio.

PS. It is just the case for Angel season I dvds I'm ripping right now.
I have to use -delay -0.25 to play them from DVD, but rips work OK without
any audio correction.

PPS. Someone on this list mentioned similar constant audio mismatch for
different (i.e. non-DVD) MPEG2 stream.
