Please help - I have a computer with a nForce 4 Ultra graphics card, and want to connect it to my TV (so it is the monitor) to watch the live Olympics streaming! My TV is an older model, and doesn't have and S-Video input, so am using an S-Video to RCA cable. For some reason the picture is black and white! The TV and PC output is set to PAL.

Anyone have any ideas how I can get the picture to be colour?
Thanks in advance!
