I always have had fond memories of DirecTV's HD picture because when I left Dish the HD was so much better, Dish was just too soft looking, but when I left D* to go to Comcast I always thought the HD quality was close and maybe equal.
I do find it sad that the best HD kind off Broadcast Picture we get is over the Internet, real 1080P ( and now 4K) from Netflix, Vudu and Amazon, don't know what Hulu is sending out ( I think 720P) but it is looking pretty also.
I hear that Comcast is working on bringing 4K broadcasts this year, with HDR (High Dynamic Range) also. It's coming, but it always takes longer than they say.
