Not sure where my issue is, but lately, last month or two, I have been noticing my local HD channels via the Eastern Arc looking terrible. The picture is very grainy to put it best. If I flip over to the off-air HD feed, the picture is normal as I would expect. This is both on my 722 and 222? so I dont know if it is the receiver. Does anyone else know or experience a similar issue, as I would love to resolve this before the Super Bowl. Thanks
