Does anyone know how to do this? It looks like you can through the media center but I'm not quite sure how. I know how to stream everything onto my 360 but I'd like to know how to get HDTV through it (not via netflix). My thoughts are that I have to get one of those HDTV Tuners for my PC and then run the channels through my computer, which the 360 will be able to connect to and run through. But I want to make sure before I go out and get a tuner. Has anyone gotten this to work?
