I don't have that problem.  I'm running with a fairly recent SVN version
of Myth, and I think that problem has been fixed.

Not that I know of.  I needed a newer kernel to run the CVS DVB drivers
to support the HD-5000.

I expect that a different chipset would correct the issues I'm having
with my SATA drive.  If I replace my motherboard, I'll also get a
different CPU, and a faster CPU might help hide the problem.  (I would
love to see a site that lists lots of CPUs by performance and heat, so I
can see what would be an improvement over my 2500+ without running
hotter.)
