[mythtv-users] Yet another NVidia 6200 1080i Component Output thread

[Eric Vaandering]

I saw this thread and with it's help, I've gotten close (maybe) to a a good setup.

My configuation:

Gigabyte GV-N62128DS board (AGP)
8178 drivers on Mandriva 2006
TV is Mitsubishi WS-65807

The TV only takes 1080i on component input. It works fine with a Comcast HD 
cable box.

I've tried a bunch of modelines I found here, at NVnews, and on the web. All 
of the ones that don't have errors exhibit the same behavior. If I switch the 
input of the TV to the PC, I can see a nice 1080i login screen for about 3 
seconds. Then the TV determines the signal is no good and switches away from 
it. Component 480i using the same signal path is fine.

Here is the x.org config file The modlines marked almost exhibit this behavior:

here is a grep of the xorg log file

I'm beginning to think the card or the driver can't output proper 1080i.

Anyone have any ideas?
