Have you actually gotten 1080i to work with component?  Can you send the 
Xorg.conf file?

I tried to get it to work from my 6600GT, but couldn't get a usable picture.  
The picture would jump up-down by a line on every frame (like the interlace 
was happening right).  Both component and DVI acted the same.  My eyes 
started to water after about 5 minutes.  I haven't found anyone with a usable 

Do you know which drivers worked?  Which list archvie were you referring to: 
nvidia or mythTV?

Any CRT that takes 1080i should also take 540p.  The only differences are in 
the timing.  Of course, LCD and plasma have to digitize and rescale 
everything; so they might act differently.
