I have a NVidia 6200 with tv output. It is connected to my TV via S-Video. My computer is dedicated as a media center and has no monitor plugged to it, only the TV.
I can see the output on the TV, but the color are really weird. Kind of all pinky. I had the same problem under Windows and had to specifically select the S-Video option in the NVidia panel from the driver to get the correct output.
I have tried numerous things under Ubuntu in the xorg.conf file (SVIDEO output type, for example), without any luck.
I was really impressed by the video of LinuxMCE, great work. I want to try it to see if it can replace my Windows MCE. Anyone can help me get the correct color output on my TV?
