Hi!
I've installed SuSE 9.0 on a PC with GeForce 5200 FX.
My problem is that I don't success display on TV by RCA output.
I think that the system doesn't load the X server, so on TV I see only the text environment and not the Linux GUI.
try installing nvtv, a software that lets you control the tv out settings of your nvidia card, it should work, if you get your tv out working please post here how you do it
