Gamecube-----------------Computer

instead of paying $100's of dollars on a capture card we were wondering if we have a ATI Radeon 9550 then there is in s-video right? so we try plugging in s-video from Gamecube---->Computer
but we can find out what to do after. someone please help. Btw the s-video is the only cord pugged in (except for the power cord)

 

you have to get a capture card. all video cards will only OUTPUT when using vga/s-video/dvi port.
