Yep.  USA.

I'm sure I have multi-path issues, but it's also one of the first TV's
that had an integrated tuner... early generation.  I recently had the
chance to use a new DVD/VCR with a digital tuner, and it worked much
better than my TV tuner.  So I'm blaming the tuner.

Well, I will have a lot of horsepower... but no need to be wasteful.

Hmm.... I'll need to do a lot more research on that then - I know it
only has one tuner, so it would only do one at a time, but a reboot to
change modes would suck.

What I gather about the HDHR is that they pick up a DHCP address,
which MythTV finds... and from then on, MythTV can control everything
(change channel, channel scan, start/stop record) over the network

Thanks for the info.
