Audio sync issues?

[Charade]

We have a 612 and a 211K. Both my wife and I have noticed occasional audio sync problems. This afternoon my local ABC channel was quite a bit off. Some of the other channels (random , of course) seem to have issues from time to time. I don't recall this happening on my older 625 and 510.

Any ideas.

There are several contributors to HD lip sync problems, from fiber optics at the local station to your TV. Don't be so quick to blame your 211K. And of course you would not have noticed it on a 625 or 510...SD.
