[mythtv-users] HDTV Modeline Help

I've got a Samsung 27" standard (not widescreen) CRT HDTV that supports 
both 720p and 1080i. I can get EDTV resolutions to work (I'm using 
640x480 right now), which is fine for most situations since I don't have 
anything media better than DVD quality right now, but I would like to be 
able to use the Desktop as well so I can remote to my desktop PC and 
browse the web effectively.

 I did a Xorg -probeonly and it did not find any compatible resolutions 
over 848x480, however I was not supprised since I've read that many do 
not have proper EDID info. It states that my hsync is 30-35kHz and my 
vsync is 58-62Hz. Using modeline calculators it appears that if I 
specify 960x720p that it is not possible to satisfy both sync 
requirements. I tried bumping the max hsync up to 45 but was greeted 
with a "jumpy" screen so it appears is that part may correct.

Hardware/Software info:
Asus A7V-Deluxe MB
Athlon 2500+ processor
GeForce MX 4 AGP video
Fedora Core 4
TV is Samsung TX-P2764 27" CRT using DVI input.
