hey,  i'm trying to get my pc to work dual screen on my tv so i can watch my movies and stuff on a bigger screen.  it's a non high def tv running windows xp with a nvidia 7600gt graphics card with 7 pin s video  i've got a 7pin s video input into the back of the card which has a 4 pin male end that i have connected into a 4pin svideo to scart cable. which connects to the back of the tv.   i run the n vidia setup wizard and it works fine but i get no output on my tv.  if anyone knows how to solve this or has a pc connected to a normal tv please let me know how you've done it.  thanks a lot.  Simon
