[MEncoder-users] Audio/Video Sync Issue

Mencoder was working for me under Fedora 11 (64-bit) but I upgraded to 
Fedora 16 (64-bit) and now the audio is way off of the video. By more 
than 10 seconds. I recompiled from SVN and still the same problem. What 
are things I can try?

The command I am using is:

/usr/local/bin/mencoder dvd://2 -nosub -aid 128 -mc 0 -ovc lavc 
-lavcopts vcodec=mpeg:v4mv:mbd=2:trell:vbitrate=900:vpass=1:turbo=1 -oac 
copy -o test.avi

The version is:

MEncoder SVN-r34980-4.6.3 (C) 2000-2012 MPlayer Team
