Okay, to be honest with you, I don't know how to fix this problem,
though, I'm sure it has to do with MPlayer's *internal* AC3 decoder.  In
MPlayer, you can decode AC3 audio streams in several ways, either with
the internal AC3 (MPlayer calls it ac3) or with the *external* (but
statically compiled!) liba52 (MPlayer calls it a52).  So, try your luck
and see if the version of MPlayer you have is compiled with liba52:
        mplayer -ac a52 dvd://1
I hope that works.  (I compile MPlayer myself from the CVS version about
once a month, and since liba52 is compiled statically, I can't tell if
MPlayer is compiled with this option or not by just looking at the info
extracted from the *.deb file!)

If that didn't work, try passing the "-channels 2" (or 6) and/or "-srate
48000" (or 44100) to MPlayer.


Tell us what you got.  As this is a very nasty bug and should be
reported to MPlayer developers (assuming they don't know about it).

Ziyad.
