I can't duplicate this on my machine (1.6GHz P4), and haven't looked at
how the threads are handled in myth(perhaps it has to do with your dual
CPU setup?).  What kind of CPU load are you seeing?  My  understanding
was that the libavcodec library took care of synchronizing, but I haven't
looked into that too carefully.  Can you try booting in UP mode and see
if you still have the problem?
