[MPlayer-users] DVD play is off-sync

When I play DVDs, the audio comes out off-sync. I have the latest CVS
version, as of last night.
The sync offset is the same when i use -vo dxr3 or -vo xv. (I have a
Hollywood+ card).
I also use the sound-out of the Hollywood+ card as my sound output, since i
have no sound card.
DiVX works just fine, though.
The command I am using to play DVDs is:
mplayer -dvd 1 -vo dxr3 -vc mpegpes   (for DXR3 output) or
mplayer -dvd 1 -vo xv    (for xv output).
The sync seems to get better when i use -mc 0, though it is still
It doesn't improve when running as root to utilize RTC timing.

libc 2.2.4, XFree86 4.1.0, gcc 3.02,
