Jim, have you looked into also streaming the video back out firewire in
the DTVLink format?   A growing number of TVs (Mitsubishi, RCA, Toshiba)
have DTVLink/1394 ports on them which you can stream mpeg2 to and the
TV displays it.  Meant for playing from cable boxes, DVRs and camcorders
(though they usually use DV, a simpler compression system than mp2)

Of course if you did this there would be extra work to get the OSD on top
(though it is possible using mpeg2's overlay bitmap stream) and getting
the UI would be a real fun challenge I expect (the simplest would be to
try to make a low-res framebuffer -> DV converter to base the X server on.)

But it sure would be nice, perfect quality, no CPU requirement to playback,
