I'm not a hardcore RF/home theater guy, but I know a bit. I hope someone can help me with my current difficulty. I subscribe to Comcast and have their Digital Cable service. My box is a Motorola DCT 2000. I currently have the baseband/RCA connectors outputtting to my stereo vcr input and the output going to my stereo TV. I have low-end Monster Video cable running throughout the system and all components are plugged into a Monster surge supressor that is connected to the same circuit. I am experiencing a high-pitch 'whine' or 'hum' on most channels, and it is espically apparent when the video onscreen goes to very light or white colors. It drives me crazy. Could this be a 'ground loop' that I've read about on the forum? Is this the price of doing business or do you think something can be done about it? I just moved into this place and haven't bothered to set up my home theater surround gear yet because of this problem.
