Extracing mp3 audio file from a movie

I recently downloaded the live-8 clips available from aol.com and wanted to extract the audio part:

wget http://pdl.stream.aol.com/aol/us/aolmusic/specials/2005/live8/london/london_004_u2_vertigo_dl.mov
mencoder london_004_u2_vertigo_dl.mov -o london_004_u2_vertigo_dl.avi -oac mp3lame -ovc lavc
mplayer -ao pcm -vo null -vc dummy -dumpaudio -dumpfile london_004_u2_vertigo_dl.mp3 london_004_u2_vertigo_dl.avi

for fl in *.mov
do
  mencoder ${fl} -o ${fl/mov/avi} -oac mp3lame -ovc lavc
  mplayer -ao pcm -vo null -vc dummy -dumpaudio -dumpfile ${fl/mov/mp3} ${fl/mov/avi}
  rm ${fl/mov/avi}
done

Works like a charm.
