graphics card AV input help

hey can any one tell me the software i need to use the input of the av ports that came with my geforce 6600? ive been looking on google for a while but i cant find squat, im pretty lost so any help would be great

 

are you sure its an AV input most cards only have an output.

 

I think that SypherTek is correct. I have an Ultra 6800 and it is an "output" not an "input".

 

damn, i thought i read sumwhere i could do that with some software... maybe i miss-read it...

i got it playing through the moniter with a TV box that plugs into the moniter i got off ebay and use that to play it , but i gotta have the PC in analough mode to play it i wanted to have it on the digital channel with the rest of my PC so i could just have the gamecube playing in a seperate box on the PC desktop through the graphics card.. anyway thanx for the help
