Hauppauge PVR 150 Help!

Okay so I just put a PVR 150 TV tuner on my PC and installed the drivers and all the other programs needed and when I scan for channles I get nothing.

So I installed my older TV tuner which is a 44xxx and installed its drivers and its programs and I get all the channels from the cable. I dont know whats wrong. Is my card bad or what?

Plz help!
