I am experiencing audio clipping or skipping when viewing digital HDTV channels. I have Time Warner digital cable. My cable box is a High def Scientific Atlanta 8000HD DVR. The skipping doesn't occur when using the TV speakers. The TV is a Sony Wega LCD Theater. It only occurs when the Pioneer VXS-D912 is doing the audio decoding. I am driving all B&W speakers, 703 fronts, HMT-7 Center, CCM80 rears, and ASW700 Sub. The front and center are bi-wired. The problem doesn't occur on "analog" cable channels. Sometimes it is every 10 sec or so and we have to turn off the AV system and just use the TV speakers. I have had the cable guys out multiple times to no avail and I now believe it must be the receiver. Obviously this receiver is not of the same caliber as the speakers. Any advice before I bag the receiver and get a new one?
