I'm using a 1080i modeline.  Haven't tried the 540p
line 'cuz I want every pixel I'm entitled to! ;-)  How
much of the scaling is due to the nVidia driver, and
how much is handled by XFree86 and myth?  If I were to
get a different card would the scaling be better?

Good idea.  I checked the manual and, alas, no joy. 
The component video input can take 1080i or 480p only.
If you get any ideas, I'm all ears.  I'm highly
motivated to get the last erg of resolution from my
system.  Football games are great to watch in hi-def,
but the field lines are so distracting.
