I have an HR20 connected to a Samsung HT-Q40 Home Theatre via Optical Audio cable. To hear audio, I select Digital In as the audio source (for optical) and I am able to hear my DVR audio in surround, with no problems. However, when I do this intially there is a noticiable delay (6-7 secs) until it begins. I also have this delay after I use the fast forward to get through a set of commercials or pause/unpause. Is this normal behavior? Thanks.
