I have been using Windows Media Center for years to record analog TV. I have both the Hauppauge HVR-1600 & HVR-1800 in different PC's. I am trying to get them to record HD (Clear QAM). I know the signal is there because when I connect my cable directly to my HDTV it can be configured to receive several Clear QAM channels. When I configure WMC it tells me there is no signal on the digital input (even with the cable connected). The PC with the HVR-1600 (Vista) allows me to tune to the Clear QAM channels (102, etc) but I get no signal using either of the inputs on the HVR card. If I try to configure WMC for the digital guide, it comes up with channels in the 2000's (all of my HD channels are just above 1000). Is there a way to get WMC to receive Clear QAM TV? Can someone point me to a web page with specific instructions on how to configure WMC for Clear QAM? Am I forced to use the Hauppauge WinTV application? FYI, this is Brighthouse cable. Thanks.
