My CRT is 1080i native but there is no working modeline that will drive it at 
1080i(confirmed by many people on the internet looking for the same thing). 
It will accept 720p via a modeline though, so i use that, granted the HDTV is 
internally scaling it to 1080i...

So I could 
A) buy a video card with an HDTV output chip and use that
B) buy a new HDTV. I'm looking to get a projector anyway and since the HDTV is 
one of those cheap Sanyo's Walmart had on sale a while back I'm not attached 
to it in any way.

and they usually suck. no offense to anyone that might have them, but I've 
never read anything good about them in the Home Theatre mag that would make 
me want one over an LCD or DLP rear projection TV, and their more expensive.
