mplayer dvd://1 -dumpstream -dumpfile uses wrong audio track

Hi,

This is mainly for others, as I have figured out the answer myself.

I normally use a little script to rip one vob file for each dvd disc title:
====
#!/bin/bash
if [ $# != 1 ]; then
  echo "Call this with the desired iso file"
  echo "vob-from-iso mydvd.iso"
  exit
fi
TitleLine=$(mplayer dvd://99 -dvd-device $1 | grep "titles")
No_Titles=${TitleLine:10:1}
for ((i=1; i <= No_Titles ; i++))
do
  mplayer dvd://$i -dvd-device $1 -dumpstream -dumpfile $1_$i.vob
done
exit
====

I'm sure that there are more elegant ways, but it works.

For one DVD, the script ripped the incorrect audio track - some English for blind people track that described everything.

What I wanted to know was how to tell mplayer to extract a different audio track.
