Problem: using a tv as a second display

[Archer1212]

ok a while back i could use my TV as a second display for watching movies through my FX5200 using the S-video port and an s-video to RCA adapter. recently i upgraded to a Gforce 4 Ti4200(odd huh that to upgrade i got an older card) wellt eh s-video on it is the 9 pin s-video instead of the standard s-video. well i get an adapter for s to RCA for the gf4 and i hook it up to the tv and i get a black screen. I figure that it might be a bad cable so i switch to a different cable and i get snow. i have it all set up properly in the display settings ive tried it on 2 different TVs and still get the same thing. can anyone here give me a hand and tell me what is wrong?
