It seems like (at least with current CVS) if I try to select a range of DVD 
chapters to play, it still only plays one, at least in my current situation.

I'm ATTEMPTING to "export" the audio from a DVD to LAME, to turn the audio
into mp3's.  It is working - I do:

mkfifo stream.wav
mplayer -vo null -ao pcm -aofile stream.wav dvd://1 -chapter 2-7 2>&1 
>/dev/null &
lame -b 96 -h stream.wav 01.lecture_one.mp3

And it chugs along...but only to the end of chapter 2.  At that point it just
stops.  I've also tried using mencoder (with the intention of doing a 
"dumpstream" afterwards to extract just the .mp3 track) and it behaves the
same way:

01.lecture1.avi dvd://1 -chapter 2-7

Chapters 2-7 SHOULD be about 30 minutes...112seconds is just chapter 2.
If I give it an INVALID chapter range (e.g. -chapter 2-1) it correctly 
complains, though.

Is this a bug?  Or am I just doing something wrong?...
