Pinnacle TV Tuner + Comcast HD Help!!!!!!? - pinnacle tv repair

I have a 801 Pinnacle USB TV tuner, is now compatible with Windows Media Center to work with him, but I see that the regular cable channels. At 2-70. In another room, we all have 900 channels. The tuner is the so-called "HD Ready". WMC shows the guide for all HD channels, but they are currently working, when I click on them. Any help would be appreciated
