Losing center audio channel

[DublinDoodah]

I'm starting to notice a recurring annoyance when watching WBNS. The center channel goes dead. When I first noticed it (I think it was during Deal or No Deal), the audio was horrible. I thought at first that I had caused the problem when I moved one of my speakers to vacuum, but found that the sound suddenly returned when the broadcast switched from one comm'l to another. Sure enough, when I changed to another station, the center channel was fine. It happened again last night after the NCAA game. When they resumed the normal programming, it was gone, at least initially. Later in the show (maybe 10 minutes), it cleared up.

Anybody else noticing it?

If you think that you first noticed during Deal or No Deal, it may be your system because I believe that show is on NBC. I regularly watch CBS HDTV programming OTA and have not noticed any audio dropouts (other than the reported problems a couple of weeks ago, which seem to have been cleared up).

I noticed this last week watching Criminal Minds; had to watch in SD until midway thru the show when the center channel came back on. This was with Time Warner cable; I was too lazy to turn on the OTA receiver and see if the problem was occuring there or if it was just a cable thing.
