Ok I found out that I can use clearQam to watch HD channels. I selected qam to be detected by Windows Media Center, but it doesn't find any channels. I go to edit channels and I can see a large list of channels with locks or no locks but none of them work. The list only has channel numbers and not the actually title. After I select a few unlocked channels they say signal is scrambled. I have Rogers Cable and Windows 7 64 bit... if that makes a difference.
