WHDH 7 NBC in Boston running hot just for The Voice?

Mods, not entirely sure where to put this so please move if you feel necessary......

My wife and I were watching The Voice premiere on Monday. I was having periodic and consistent audio dropouts.

No other channels were doing this so I thought, maybe channel 7/WHDH/Boston NBC was running hot.

Other anecdotal evidence...

- The Voice from last night exhibited the same behavior
- Still no other channels doing this
- Went to other NBC recordings from yesterday (Jimmy Fallon, etc) and no other occurrences
- Went to older recordings from NBC and still no other evidence

I think I have ruled out HD problems as it ONLY seems to be happening on just one show on one channel.

Very weird.

Anyone have thoughts? Is it possible my local comcast runs the channel hot just during that show?

I went in to the signal strength meter and right now all my channels are at about 90%+- so nothing seems to be running hot right now.

Is this something I should report to my local Comcast office? And would they even know wth I am talking about?

Thanks ahead of time for any input!
