Linux comes with all the drivers it has or needs, generally. If your hardware is not recognized, there probably isn't a driver for it, and it's not going to work. Many TV cards do work fine under Linux. I'm not sure what "video driver" you're trying to install, (proprietary?), but if the video works, why are you trying to install something else? The default should work. If you were more clear about what exactly you're trying to do, you would get more help. You need to know exact models and chipsets of cards to determine if they will work or not.
