When you're reporting a bug or usage issue, it's always best to try to
narrow a command down to a certain option (or sometimes more than one of
them) that causes your trouble. Not only does this reduce the effort on
the part of anybody who may help you, it might direct you to the source
of the problem so you can write a more direct bugreport.

So, I would say, try getting rid of the -info, video-related lavcopts,
video filters, and -sws:

mencoder dvd://1 -dvd-device /home/prova/DVD/UNDERWORLD -chapter 2-2 \
-aid 129 -oac lavc -ovc lavc -lavcopts acodec=ac3:abitrate=128

That's a much cleaner line to look at, and I suspect you'll have the
same issue. Then try using "-oac copy" and see if the audio is ok.

...also, I just noticed that you're running 1.0pre5. MPlayer development
moves quickly enough that releases are obsolete after a few days, let
alone after over two months. Use mplayer CVS with libavcodec CVS and see
if you still have the same problem.


By the way, when you're starting a new topic, use the "compose" function
of your mail client rather than "reply" - if you reply to an existing
mail, your new topic will end up buried in another thread rather than
starting a thread of its own. You'll see what I mean if you enable
threaded view in your mail client.
