I decided to test this and, uh, I can't make it work.  Mencoder just 
hangs on the first frame.  Can anyone see something that I'm doing wrong 
here?

I'm using this command line:
mencoder dvd://1 -dvd-device /dev/hdc -audiofile audio.mp3 -vf 
crop=718:366:2:54,scale=704:304 -ofps 23.976 -oac copy -ovc lavc 
-lavcopts [bunch o' stuff] -o darko.avi

this plays just fine, however:
mplayer dvd://1 -dvd-device /dev/hdc -audiofile audio.mp3 

I've tried it with many different mp3 files, and a few different DVDs, 
but the same thing happens.  It does seem to work if I give it audio.wav 
as the audio file, but why would I want to do that.  I've tried it with 
pre-4 and the latest CVS.

Mencoder output:
