What is going on with DTV's picture quality? It has been degrading now for some time but I don't know for how long. Just about all SD channels now looks like crap. This includes heavy pixalization, blurriness, and all kinds of other "artifacts". Basketball this weekend was unwatchable on all channels and looked like an Internet feed. I'm very unhappy and after watching some recordings from a few weeks ago it's quite noticeable on how poor the picture quality is today compared to a few weeks ago. What is going on? The picture quality is now unaccaptable. And this is on a 27" inch TV which is a shame. Have any of you noticed this?
