error media center ir hardware not detected

Media Center, how do I watch tv with it? I
I have a Hauppauge WinTV PVR USB2 external, hooked up to a Pioneer set top box from Time Warner. My IR Blaster is a USB-UIRT. Vista finds the driver just fine and installs it. I have Snapstream Beyond TV running okay. I use the remote from Time Warner to change channels, or I click in the Beyond TV window. When I try to run Media Center setup, it tells me "IR Hardware not detected" and tells to cancel.
