[mythtv-users] 16x9

I've read a bunch of different postings and some Wiki information 
surrounding displaying on a 16x9 television screen, but some of the 
information seems to conflict.  Add to that a sprinkling of confusion, 
and, well, I just don't get it.

Should I adjust my xorg.conf file to set the proper DisplaySize as 
listed in 
http://www.mythtv.org/wiki/index.php/XorgConfMonitorSectionForTV?  And 
that wiki seems to have a little touch of the "black art" feel to it 
with "it is advised to play with the value..."

Should I adjust the settings on my nVidia card to try to display at 
1080i or 720p (one TV supports both, the other goes up to 720p) with the 
black art of playing with modelines and such (the 1080i capable tv 
(older big rear projection) only has component in, whereas the 720p 
capable tv (LCD) has VGA in, too)?  With that, there's the fight of the 
right modeline, overscan, tearing, etc.. 

And, if I step back.. is this really a two-step issue?  First get it to 
display in 16x9 fashion at, say, 480i, then try to do additional steps 
to bump the resolution up to 720p?
