Joel,

I'm running a Sony plasma that is 1024x1024 (it's an unusual
resolution). Currently, I'm going through an RCA VGA-> Component
adapter, very similar to the AA960. Below is a snippet from my
xorg.conf. I've got a new MythTV system in the works set to replace
this one with DVI out on an NVIDIA 6150 chipset, but I haven't been
able to get 1080i out of that one yet.
