I've got a NVIDIA 6600GT which has HDTV output support, and I still can't get 
a usable 1080i signal.  It will put out 1080i, but the picture jitters 
up/down (like the interlace isn't timed properly).  It's unusable.  You're 
eyes start to water after a couple minutes.

I tried two different TVs, and both act the same way.  Both the component 
outputs and DVI act the same way.

This is from Fedora 4 with the current NVIDIA drivers (as of 4 months ago).  I 
can do 540p or 720p fine.  Note that not all sets that support 1080i will do 
720p.  The 720p signal has a higher horizontal refresh rate and my Panasonic 
can't display it.

Stick to progressive.  It will save a lot of headaches.

If anyone has gotten this to work, I'd love to have the modeline.
