Just out of curiosity, why are you doing that? If the audio is low
quality, re-encoding will only make it worse.

By the way, an easy way to redirect stdout and stderr to a file is to
use "mencoder blahblahblah &>mplayer-bug-output.txt"

At least with bash, that is; if you're using another shell, then maybe
disregard that.

Can you at least give us the text mplayer outputs, but only with one -v,
please :).  I'm not familiar with what you're doing, but I or someone
else may be able to understand the error if you give us the output.
