My theory is that the digital signal is too fragile. If you don't have the bandwidth in your processing, converting, or transmission equipment, you suffer from digital problems. Just like digital distortion is 10x worse of a sound than analog distortion is, in the audio world. Progressive Scan DVD's look phenominal on my projector, and that's just straight component out of my DVD, through my receiver, and into my projector. HBO HD and Skinamax HD both look even better. The broadcast channels I do get often are crap. I've been reading several forums about my local HD channels and their problems, and it seems that most of the problems are originating either with the network feed, for which I hear nothing about, at the station when they upconvert(worthless-ize), or at the transmitter. So I'm guessing DTV is just too new and hasn't had all the kinks worked out before it was pressed into action.
