The last 2 days I have been having audio/video sync issues while watching LIVE tv. Not always on the same channel. A full hard reboot did not help. Sometimes a skip back does fix it. A skip forward or a view tv command to get back to live tv will put it right out of sync again. This is a 1 week old 522, and we never noticed this the first week. An archive search shows that this happens to alot of people while watching a recording, but this is ridiculous. This is on tuner 1, with tuner 2 turned off and nothing recording. Is this a new 522 issue, or common?
