When I first got Directv a couple months ago I thought the picture was a little grainy, more so than when I had Dish. I have a 57" TV so I can really notice the compression and artifacts. After about a month the PQ seemed to improve quite a bit, especially on certain channels. Does anyone know if anything was changed by DirecTv to affect PQ? The PQ is so good now I'm not as anxious to get HD anymore.
