Has anyone experienced "Audio Pops" or dropouts when watching NBC Nightly News in HD,,,, over the air only? I am trying to find out if this is a local or widespread issue.

Interestingly I hear no pops during the Network commercials, only during the newscast. Appreciate any confirmation or not. I only have noticed this on this one specific program on NBC.

Please indicate your receiver type if you reply. I use a Dish VIP 622.

I ran through the other related threads but could not come to any conclusions.

Thanks!
