Media Center PCs only support broadcast HD, but there are graphics cards from ATI that support HD.
I have a Media Center PC with a TV Tuner card and an ATI Radeon x600 pro graphics card. I also have a 19" LCD flat panel display. My question is if I use an HD Tuner Box from Comcast for my cable TV and I run the coaxial cable into the pc, will I be able to watch HDTV through the Media Center app?
