Both 720p and 1080i source driving a 50" plasma at 720p resolution via VGA (my plasma TV has VGA, component and DVI input but unfortunately my FX5200 doesn't have DVI or component).

Window manager?  Who needs a window manager? :-)

Largely nothing adverse happens.  There might occasionally be a skipped frame on startup, but I think that has more to do with swapping and HDD speed than CPU.  Most of the time I don't even get that.

Bingo.  Took me a few minutes to play around with the various
MythTV, Xorg and nVidia settings to come up with something
optimal.  Extra audio buffering turned out to be a big one.  I set all that stuff up about a year and a half ago, so I can't recall all the details of what I did.  But if you are really curious, I can post some (edited!) excerpts from my configs.
