[mythtv-users] On nVidia 6200 can run SVIDEO TVOutFormat, can't run COMPONENT

I've got a Leadtek Winfast A6200 card that's supposed to support 1080i.  But in Xorg.0.log, these are the resolutions it reports my video card supports:

The highest desktop resolution the nvidia driver is reporting (in Xorg.0.log) that my card supports is 1024x768.  Since my card says it supports 1080i on the box, it's like some resolutions aren't "visible" to the nvidia driver.

My graphics card manual says that all the NTSC resolutions (which are all the ones in the last above) are supported by S-Video out.  The higher ones, including 1080i, are supported by the component out.

So, I've been trying to put the nvidia driver in "component mode" to access these higher resolutions on my graphics card by modifying xorg.conf.

When my television is hooked up to my graphics card via an S-Video card, I can put a "TVOutFormat" "SVIDEO" line in xorg.conf, I get a fine (but blurry) picture on my television.

Then, I switch it so that my television is hooked up to my graphics card via component cables.  I leave the "TVOutFormat" "SVIDEO" line in xorg.conf, and I get a pretty good image on my television, but it's in black and white.

So, I change the "TVOutFormat" line to "COMPONENT" and restart X.  Now, I don't get any picture at all.

It's like the nvidia driver is having trouble accessing the "component mode" on my graphics card.

Maybe there's a way to get component video working?  Is this just a bug in the nvidia driver?

Thanks,
