HD Broadcast Audio cuts in and out ...

Hi,
I was wondering in any one knew anything that might cause my HD Broadcast Audio cuts in and out when going thru my HT system? I have standard tier cable (time warner) and have no cable box or card, just coaxal directly from the wall to the HDTV. I have a toshiba 56" HDTV and I am running optical out to my B&K Ref 50. I have tried different optical cords and determined that it is not the cord, also have determined that it is not the particular input on the ref 50, by trying the cd and dvd input which work fine with their players. When the audio cuts in and out (not constantly but just now and then) the HDTV's audio does not. ( if the tv's volume is up) What I was wondering was if it is the processer or the HDTV? Or maybe just a problem from the broadcast with compression or just processer speed? Any help would be great.

Often times the broadcast has a blip in the Dolby Digital track, but not in the stereo audio downmix. That would explain why the tv isn't affected. Over the last 3 years of watching HD, I just expect it now and then. If its too bad, I just go back and rewatch on Tivo with the audio settings different (DD off) or if its really bad, I have to turn on the close captioning.
Some stations are worse than others. In my area, I've had the most problems with NBC and ABC. Fox and CBS rarely audio problems in my experience.

Thank you, I was hoping that it would be something like that. I did not want to think that it was my TV or processor. I am new to the HT world and have just had my Ref 50 for 1 week, ant HDTV for 6 months.
