The whole scenario still sucks, though.  If you can't decode the stream 
before it's output, you lose half the functionality of Myth.  No 
commercial detection, no input/output filters, possibly no OSD, 
depending on the output mechanism.  No transcoding to save space.  No 
(or at least limited) seeking; no trick play (slow down/speed 
up/libsamplerate stuff).

At that point I would probably have to break down and get a Tivo.
