Can anyone tell me if they are noticing mosquito noise, especially found in the background areas on HD channels? I am noticing alot of this noise and is ruining my picture quality. It doesn't happen all the time and seems to come and go lasting for days at a time. I have tried everything possible to track down this problem to no end. I can also see this noise OTA through my 722k. Any suggestions? BTW I have 1000.2 setup.
