I'm seeing 100% CPU usage with mythbackend while recording, regardless
of whether the frontend is playing.  I haven't had a chance to check to
see if it was pegged when the frontend was killed.  strace of
mythbackend during pegging indicates uninteresting levels of system
calls, making me guess it's in the compressor or something along those
lines (but that is just a guess).
