Here is my setup: Panny XR50 LG LST-3510A HSU VT-12 Speakers Scientific Explorer 3100HD Cable Box I am experiencing audio dropouts on my receiver. While watching U-571 earlier, it happened more than a dozen times. It even happened while I was still on the disc menu. I can see the speake and Dolby indicators going in and out of the XR50 LCD display. At first I though it was just the DVD coax input of the receiver so I switched the coax cable to the CD coax input. I still experienced the dropouts. I then thought that it's probably my DVD player. But when I plugged in my HD Cable Box to the receiver and watched some HD channels, I again encountered the dropouts. I don't have an optical cable to test but will probably need to get one for testing purposed. I just want to know if anyone has ever encountered these audio dropouts on their XR50. Maybe I will try analog inputs. On my receiver, I have setup the front satellites as small and the center as large. Do you guys have any other idea on how to fix this or maybe isolate the problem? Thanks! Any help is greatly appreciated. BTW, I am using a GE prograde coaxial cable.
