Can i reverse S video output on my vid card to INPUT?

i have an Nvidia GeForce 8500GT 512mb and it has S video, i want to plug my TV into it, but i need to reverse the S video jack to make it INPUT on the video card. its already set to output on tv now i need input on my comp so i can watch TV.... so is there any way i can reverse the S video output jack? the tv is EDTV (like HDTV) and has many jacks but the S video on it you can switch from input to output so i was wondering if you could on the computer, i have Windows Vista home Premium and the TV is detected through S video, but how do i put the S video jack on the video card to input... it is NOT an onboard card i bought it seperately, it is PCI-Express PLEASE HELP thanks|||In a word

NO

But you CAN buy a USB video capture solution . . .|||No, sorry.|||Generally, if any jack is marked INPUT, it's INPUT, and if it's marked OUTPUT, it's OUTPUT.



Sorry.
