Thanks Sonnie; I'll ask the cable guy when he comes this AM. The two techs that were here yesterday didn't even know what Dolby was so I don't give much hope on help from them. The pulsed noise looks like Pulse Code Modulation (PCM) on the A/V display. I have never heard PCM so I can't be sure that is the noise. Scientific Atlanta's web site doesn't give any info either. I don't think its the A/V receiver and hate to buy another one right now just to find out.
