The problem with cable is every time they add HD channels they compress everything even more and PQ drops. With our local cable company, the compression is so high it is difficult to tell a HD program from an upconvert. My buddy was amazed at the PQ on an ESPN (not the best HD) bowl game when he was over the other night because, in his words, it is "as least twice as clear as cable" and we both have 42" LCD's.
