Thanks for everyones help and commentary on what my hardware can
achieve.  I only have to figure out the /dev/rtc permission issue and
oversized desktop to screen.  I will try the newer NVIDIA drivers at
some point.  For now HDTV playback is much better than before with
Temporal 1x for high-motion (hockey) playback.

FWIW I've put a blog entry together for my own memory & possibly to
help others out (and capture some of this information in this thread).
 I've kept notes on this stuff previously but hopefully I can keep
this blog up-to-date with a working system overview.


I also updated a couple of mythtv wiki pages about
tearing/deinterlacing with a couple of sentences about the Composite
issue... hopefully help others towards finding solutions.

Thanks again!
