Not sure if anything has changed recently but today DISH HD looks more pixelated than usual. We have been watching ID and it's really noticeable there.
I had ID on for a while today, just got done swapping between Nascar and Phillies/Braves game (ESPN and MLB alt) all HD with no pixelation at all. EA as well.
We've had HD on Dish just about since they started offering it and have never had any pixelation ever. THe only caveat is that I'm in Phoenix, so we don't have any weather either. Sounds like you might need a service call?
