Upon reading your post, I noticed that you were using component video
outs. I'm connecting to a Standard Def TV and would like to use the
component out. When I boot up using the component out, I can see color
in the console (prompt, directory listings), but as soon as I start X,
the color is extremely muted. The only thing I can make out is the
bright red which appears slightly pinkish. The rest of the colors
appear black and white, or are so muted that I cannot make them out.
The colors are fine when using the S-Video output on the breakout box.
I am using a 256MB GeForce 6600 PCI Express card (Gigabyte
GV-NX66256DP). The TVOutFormat setting in xorg.conf is set to SVIDEO.

Have you, or anyone else on this list experienced something similar.
If so, could you please share how you solved it.
