This is how I extract audio and convert to MP3.  Should work for any format
that MPlayer understands, audio or video.
1. mplayer -ao pcm FileName.wmv (This creates a file named "audiodump.wav")
2.  lame -m s -q 2 --vbr-new -V 1 -B 320 audiodump.wav OutputName.mp3  (Lame
changes it to an mp3)
Of course you need lame and mplayer and the proper codecs.  This is very
useful for dumping streaming audio as well.
