lavc mp3 just calls lame, so you're better off using -oac mp3lame
directly instead.  Perhaps then it won't crash with 2ch audio.

You can always try -mc 0 / -mc 0.01 / -mc 10 / etc.

Without "-of lavf" you're just encoding to an AVI file.

Nope.  Look at the output of mplayer when using "-ao pcm", it tells you
how to speed-up audio output, using "-vc dummy" and a few other
options.
