Tonight while watching a recording of 'Heroes' in HD (OTA) on NBC , my wife and I noticed random 1-3 second skips (both audio and video). Often we missed complete sentences. However, we could go back and watch the same part again and catch what we missed. So it appears to be a playback problem and not a recording or signal reception issue. Both the audio and video are skipped for a few seconds. There is no picture break-up, distorted sound or black screen when this happens. Its just that we periodically are missing a few seconds of content. While watching Heroes, this happened on average about 2 times every minute. We've noticed this many times in the past on other HD recorded shows. I called Tech Support and the man said he had not heard of this problem. Has anyone else experienced this?
