The mjpegtools can only handle AVI and Quicktime files with video codec
mjpeg, and for audio wav. What you see is that the mjpegtools are not
able to handle the AVI codecs used. the output should be more like that:
VIDEO:  [MJPG]  720x576  24bpp  25.000 fps  22732.6 kbps (2775.0
kbyte/s)
Selected audio codec: [pcm] afm:pcm (Uncompressed PCM)

You can get the audio from the AVI file with mplayer if you use a
command like that:
mplayer -ao pcm -vo null file.avi.

Than you should get a audiodump.wav file you can use. 

auf hoffentlich bald,
