(Sorry if this is a repost, but it never made it back to me from the
mailing list, so... )

Hello folks, I'd like to ask for some help getting my X resolution
correct for mythTV. X is currently locked at 640x480. I'm handy at the
*nix command line, but X Windows is not really my forte, so any help
you could offer would be appreciated.

Here's my setup:
Motherboard: K8NGM2-FID. It has VGA, DVI and RGB component video (TV-out)
onboard, using PCI-Express and an Nvidia GeForce 6150 chipset
(http://www.msicomputer.com/product/p_spec.asp?model=K8NGM2-FID&class=mb)
PVR-500 x2
Sony KE-42TS2 Television. Connected via DVI-D.
Fedora Core 5 with NvidiaGraphics8756, all updates from atrpms

Here's my (mostly default) xorg.conf. The Monitor section that's
commented out is what worked with my old MythTV box (got it from
Jarod's guide). According to the user manual for the TV, the native
resolution is 1024x1024 with rectangular pixels. It does 1080i from my
cable box over DVI quiet nicely.
