1. Debs from marillat.free.fr aren't supported here (issues I don't know
and therefore won't get into). Download the source of 0.90rc4 or the
latest CVS, and compile. If you want, you can make your own custom debs
from the source. Short version:
$ export DEB_BUILD_OPTIONS="--option1 --option2"
$ #replace the options above with what you want to pass to ./configure
$ fakeroot debian/rules binary

2. Sometimes the DVD audio stream isn't correctly detected. Try
$ mplayer -dvd 1 -aid 128
or 129, etc. If this doesn't work, you ought to upload a sample to
$ mplayer -dvd 1 -dumpstream
and press CTRL+C when stream.dump reaches 10 MB or so. Send this and a
descriptive text file to the above ftp.

3. On second thought, upload a sample and text even if you can get the
audio to play with -aid. Thus, the developers have a chance to improve
the autodetection code.

4. In the future, if you have a problem with mplayer read
DOCS/bugreports.html, and, _at_the_very_least_, include the full output
of mplayer when trying to play the file you have trouble with.

Have fun, :)
