You can use the video capture API to do tv tuning, but I have not yet found a way to programatically access the radio functions in Windows. I think that appropriating some DLL's from the software that comes with it may be the best way to go about it..

I've tried that. Pulling the DLL in VB didn't allow me to do squat. "You do not have a license to use this driver." As usual. Best thing to do is ask the OEM for SDK or some type of source for "Personal" use. If you don't mention the "Personal" part, they will consider you commercial.
Well, generally to do this sort of thing with VB you have to analyze the function calls in the original DLL, write a wrapper as a DLL or OCX, then import that. It's a headache but it works
