I am trying to set up a "media center" at home, using Windows 7. I have an HDTV already. I just bought an Iomega Screenplay Director (media player) for playing torrents and have a nice Denon reciever. I also have CC high speed internet(18Mbs). What I want to do is to be able to install an excellent HD video card to my computer to watch and record as many programs as possible by just using a Comcast basic subscription and eliminating, or downgrading, their set top box (if possible). I believe it can be done but need advice/help. Even if it requires a "hybrid" system with an over the air antenna in the mix. The idea is, get as many quality HD channels using the minimum Comcast plan. I may still need their box for HD? It takes some imagination. So, what have you experts got?! thanks
