It's been just over a week since I have upgraded from the 622 to a 722. I'm on my 2nd 722 in that week period. Now I am noticing more problems with the replacement unit. Audio dropouts and pixelation problems are ongoing. I have checked my signal when the pixelation happens and it seems to be fine (~70). I have done a hard reset which hasn't helped and I have tightened all of the coax connections at the back of the receiver, they were left very loose by the Dish install technician. The thing that I am noticing is that the pixelation seems to happen quite often after a show starts up just after a commercial. Anyone have any insight on this type of problem with the 722?
