I can't play DVD but I can't encode.
It seems to be a bugm the AC3 audio is interpreted by mplayer as correct 
5.1, bu mencoder thinks it's 5.0:

tomek at mcoding:~$ mplayer dvd://1 -chapter 2-2 -vo null -ao null -frames 1
MPlayer 1.0pre3-3.2.3 (C) 2000-2003 MPlayer Team
[...]
Opening audio decoder: [liba52] AC3 decoding with liba52
Using SSE optimized IMDCT transform
AC3: 5.1 (3f+2r+lfe)  48000 Hz  448,0 kbit/s
[...]

Any idea how to solve it?

thanx inadvance,
