For the most part I avoid watching SD channels whenever I can but I have noticed some improvement in my SD locals. I think the improvement is due to the fact that DISH is now picking up the local OTA digital feeds (instead of the analog feeds) and there is not as much "interference" type problems. As far as compression artifacts they are as bad as ever on my locals but that is because DISH is putting several cities on that spotbeam. Hopefully, when Echostar XI goes into service (this week) and they balance out the channels from 110 the picture will improve.
