The audio doesn't cause the problem...  The video doesn't cause the
problem.  Both of them together do.  Mencoder needs to read further
ahead in one than the other, but MPlayer blocks until both are read.

The only fix is to use two seperate instances of mplayer, one just
writing audio to a pipe, and the other just writing video to a
pipe.
