[mythtv-users] Looking for help with xorg.conf

My video out card is a Leadtek WinFast PX6200 which linux sees as a 
"nVidia GeForce 6200 TurboCache". In nutshell it has DVI out, VGA out, 
and a port that takes a dongle that gives me s-video and composite out. 
I'm trying to setup a dual-head display that goes to my TV and the DVI 
port, but everything I seem to try gives me a blank screen everywhere 
following a CTRL-ALT-BACKSPACE, forcing me to ssh in and revert to the 
original xorg.conf. Basically, I want to enable DVI out to a 17'' LCD at 
resolutions of 1280x1024, 1024x768, and 800x600 with 32bit color. I 
*also* want to go out to my TV which is a JVC 61'' widescreen plasma 
(HD-61Z456). And, of course, I'd like the TV out to be widescreen (16:9) 
resolution(s) since all my DVDs and rips are widescreen format. I was 
able to disable the LCD section and enable an option for "TVOutFormat" 
"SVIDEO" and I could get a signal on my TV, though it had a border all 
around and wasn't very sharp. Unfortunately, trying the composite cables 
*and* "TVOutFormat" "COMPOSITE" didn't seem to work. The config below is 
all I've been able to get to work for the TV:

Section "Device"
        Identifier  "Videocard0"
        Driver      "nvidia"
        VendorName  "Leadtek"
        BoardName   "Leadtek WinFast PX6200 - nVidia GeForce 6200 
        #Option      "RenderAccel" "1"
        #TV Out Setup
        Option     "TVStandard" "NTSC-M"
        Option     "TVOutFormat" "SVIDEO"
       #Option     "ConnectedMonitor" "TV"

... but doing this gave me TV out only, not DVI out as well... so while 
I can see it somewhat decently on the TV, its blurry enough that I have 
to use my LCD monitor to fix things (or a remote console via ssh), but 
since I can't seem to get both the LCD and TV going at the same time, 
this is getting quite frustrating.

I'm pretty decent with linux, but not so hot with A/V. Could someone 
(preferably with a similar card and/or TV) help me with a sample 
xorg.conf that goes out to DVI and TV (preferably via composite, but 
s-video will do) and that uses normal resolutions for the DVI, but 
widescreen resolution(s) for the TV?
