I feel like an idiot but...
Ok, I have a new Media Center PC, and it came with a video card that has a TV tuner. It is an NVIDIA GeForce 6200 TurboCache. The TV itself works amazingly in the Media Center program, but there is also a spot for red, white, and yellow AV cables to be inserted. I plugged my PS2 cables into it and turned the PS2 on...now I can't seem to find the option to switch to video in on the Media Center program. Am I missing something?
