Suppose you don't try to dump the 3-minute section and instead just play it. 
Does that work? If it does, you can try MEncoder instead of MPlayer.  I have 
never tried it myself, but the "aconvert" script in the TOOLS directory 
allows you to encode from an audio-only file.

Maybe the file is too big for MPlayer. The negative numbers and gibberish at 
the end don't look good.
