I think fixing the decoder bugs is a better goal. Kenneth recently
posted some patches for the mpeg decoder which may well help with the
problem you are describing.

BTW, does anyone have any experience with high definition TV on Myth
(ie high-level MPEG)? I get nonstop errors from the decoder in the 
frontend trying to watch it. I don't know if that's because it's having
problems with the sound (AC3 only, but I'm not using the AC3 passthrough
