I DVR'd the NBC LAX show and I heard a click on the MOXI DVR (about ten minutes into the show) and noticed that audio did not match what the characters were saying. I replayed LAX and the same thing happened. When LAX went to commercial the audio and video were in sync. After the commercial everything was in sync. At this time I can't be sure if it was an NBC problem or a MOXI DVR problem. My first guess would be MOXI because I heard that click on the DVR before the out of sync happened.
