I'm in central Maryland, and I also had audio/video break ups and frozen pictures last night too. As a matter of fact the MLB channel went out completely, while I was watching the Yankees/Dodgers game. The trouble shoot menu popped up, and said there was an outage in the area?
All is back today.
I did notice tonight, that in some guide listings, it now shows the word Dolby with the double D icon.
I guess this is new.
