Nope, the only problem is the signal Dish has stepped on.
I have 2 Pioneer Pro-Elites (Retired) both professionally calibrated (one brought back out of retirement for comparison to check Dish signal), a Sony 75" 900e, Vizio P 65" calibrated by me, well a friend, who has the equipment. I definitely have them calibrated as good as they can be for the Dish source + streaming & DVD's.
I should say that overall Dish has a good product. The features are very-very nice, they just need to provide a better quality of the signal. I understand the pipe only has so much room, so quantity (Make the customer happy with an overload of choices!) trumps quality.
