I just got a hauppauge pvr150mce (the real one with fm receiver)

I was looking for a small program to listen to the fm part of it. I know I can use some of the tv cap programs, but i was looking for something very small. Maybe something that I can just minimize and listen to the radio with out noticing ANY performance issues, or slows.

And hopefully the program will load quickly...unlike tv cap programs.

Thanks
