FYI, we've verified that this is a threading bug in the player.  The
same problem occurs under Linux when playing video and audio
simultaneously.  I have an utter hack that mostly works around it
under NetBSD -- in kern_sig.c:sigsuspend1(), change PPAUSE to MAXPRI.

The next task is to get ac3dec and mpeg2player to build natively...
