And it looks REALLY good too.

This part I don't quite understand.  Selecting inputs should work just like
with the BT8XX based cards doesn't it?  Myth does seem to get this right
when using rtjpeg & mpeg4.  Also even with hardware-mjpeg enabled and
watching live tv it still switches inputs using the "c" key.

Just as a test I captured some clips with the mjpeg tools, 1 at decimation 1
and 1 at decimation 2.  Mplayer can play back the decimation 2 clip using
around 20% of one cpu on my dual Celeron 500 box but the decimation 1 clip
is at 90%+ and having problems.  Any chance decimation levels will be
supported?
