It appears I may also be having ground loop problems. Doing some reading, it appears that the artifacts I'm seeing are consistent with those generated by ground loop problems. Those problems aside, the picture quality with these avovernet baluns just isn't quite good enough.
I can work on some solutions for the ground loop issues but not sure even if I get them resolved that I will be happy with picture quality. I'm curious if I can get satisfactory picture quality with baluns, even if I go with the more expensive active baluns.
Robert, it appears by reading through the threads that you are a big fan of the CE Labs active baluns. I may buy a set of these and give them a test drive; this would resolve my IR problem and my D/A issue on the other end for most of my TV's. Would the fact that these baluns are active possible resolve my ground loop issues? The downside is I need to run additional cat5 which is troublesome but possible in most of my locations. If I have to run additonal cat5 lines should I run cat6? Is a specific type or brand of cat5/6 a better option for video distribution?
Does anyone have recomendations for alternatives to the CE Labs Baluns that provide the same functionality (component, ir, analog & digital audio) ?
