Sounds like a ground loop problem between your cable TV line and a component(s) in your system. As a test, when you watch a DVD movie or VHS tape do you still see the rolling scan line? If so, physically disconnect your cable TV line and I bet it goes away. Also, is part of your system plugged into a different outlet than the rest, i.e., a projector or amp plugged in at the back of the room? This could cause to the problem.

The easiest immediate solution is to use a ground lifter (3 prong -> 2 prong outlet plug) on the offending component or on your power strip. Any thoughts on this?
