For one thing, 'frameno.avi' is an almost completely obsolete feature,
and has nothing whatsoever to do with your problem; it is used only in
an outdated three-pass encoding process.

The problem is that your particular version of MEncoder does not
understand the 'rawaudio' output format. It was added in June of 2005,
and 1.0pre7try2 was released in May. Either read the documentation which
should have been installed when you installed MPlayer, or (if you want
to go by the online documentation) download and compile the current CVS

Your command line above should be correct, if you use a version of
MEncoder which supports -of rawaudio.

If you don't want to or can't do that, then your only real alternative
is to say

mplayer input_file -ao pcm:file=output_file.wav

and then use your favorite independent MP3 encoding tool to turn the new
WAV file into an MP3. This is not quite as ideal, because it will
probably be more lossy than doing it all in one step with MEncoder, but
it should get the job done.
