[MPlayer-users] Dumping specific audio stream from a DVD

[petesea at bigfoot.com]

Is it possible to dump the video and only a specific audio stream from a 
DVD?

I've used the following to dump a title from a DVD and it works fine, 
except it always dumps all the audio streams:

   mplayer dvd://1 -dumpstream -dumpfile movie.vob

What I'd like to do is this, but it doesn't seem to work:

   mplayer dvd://1 -alang en -dumpstream -dumpfile movie.vob

or in some cases, something like this, but it doesn't work either:

   mplayer dvd://1 -aid 131 -dumpstream -dumpfile movie.vob

Here's example output from this last one, which was run on a MacBook Pro 
(OS X 10.5.2):

   $ mplayer dvd://1 -aid 131 -dumpstream -dumpfile movie.vob
