For some reason, I cannot for the life of me get the FM portion of either or my Leadtek Winfast Tv2000XP's to work. I bought two (one for inside, and one for the car).. Does anyone have any tips or tricks to get this working?

The TV function works fine, but I cannot get ANY sound from the radio. No static or anything. I have tried both the fm player that came with the card, and Radiator (although I am not sure if Radiator works with it)
