Hey Rich!

I just got around to getting the DVI->HDMI cable hooked up, and I can't 
get it working from within Linux.  When my Myth box reboots, I can put 
my TV on HDMI2 and see the boot up process.  However, once the X server 
starts, I get nothing.  I don't see anything in my /var/log/Xorg.0.log 
file that indicates any problem.  I tried to follow the link in the Wiki 
that you sent, as well as the following article to no avail:  
http://www.fedoraforum.org/forum/showthread.php?p=721770#post721770.

Here are the relevant sections of my xorg.conf.  Any ideas on what could 
be wrong?  I'm actually curious as to whether or not the NTSC-M for 
"TVStandard" is correct.  The above FedoraForum thread references HD720p.

Section "Extensions"
   Option    "Composite" "Enable"
EndSection

Section "Device"
    Identifier  "Videocard0"
    Driver      "nvidia"
    VendorName  "nVidia"
    BoardName   "NVIDIA GeForce"
    Option      "TwinView"
    Option      "TwinViewOrientation" "Clone"
    Option      "ConnectedMontior" "CRT, TV"
    Option      "SecondMonitorHorizSync" "30-50"
    Option      "SecondMonitorVerRefresh" "60"
    Option      "TVStandard" "NTSC-M"
    Option      "TVOutFormat" "Composite"
    Option      "TVOverScan" "0.6"
    Option      "MetaModes" "1024x768, 1024x768; 800x600, 800x600; 
640x480, 640x480;"
EndSection

Section "Screen"
    Identifier "Screen0"
    Device     "Videocard0"
    Monitor    "Monitor0"
    DefaultDepth     24
    SubSection "Display"
        Viewport   0 0
        Depth     24
        Modes    "1280x960" "1280x800" "1152x864" "1152x864" "1024x768" 
"1024x768" "800x600" "800x600" "640x480" "640x480"
    EndSubSection
EndSection


Thanks,
