Hi funkenbooty!!!
Yeah, the way to fix it is downloading and installing the official drivers. The generic drivers do not provide you with truly 3D support neither with TV-Out.
After getting it to install though, you will be surprised with speed you can get with nvidia and 3D games... Return to Castle Wolfenstein is so smooth you won't believe.
You can get the drivers here:
www.nvidia.com
They are pretty easy to install. Search the forum with the search button about installing Nvidia drivers. Should not be to hard...
Good Luck
