Hi
I recall now to what show I heard this on recently. They had the heads up poker championship from 11 to 1 pm that i would record and play back at night
It's an NBC show and for some reason during the Hockey game I got this same audio issue ( game was right after the poker broadcast but it's not live )
Now last night I watched the Apprentice on NBC and it was FINE! No issues at all.
So it's just this one local it seems and it's on two receivers and two TVs i have had for 5 years so it's the channel or the signal I get from DISH and it's not happening all of the time but i've caught it more than once.
Again, I did not get this when i got NBC from Birmingham Alabama for a few years. Swapped to Meridian recently and only then did I catch it acting up. I do not watch much network during non prime time hours.
So Two diff receivers, two TVs one using component and the other is the back TV using coaxial.
I talked to a adv tech last night and they agreed it's not on my end. It is just odd it's just this one channel and last night it was fine when i watched prime time broadcasting. Even that hockey game was ok between periods and commercials.
Thanks
Tiger
