I've noticed that I get a faint pattern moving from left to right every second or so, and was wondering if anyone who has Sky+ has seen it. The pattern quite difficult to see at first, but once noticed, it distracts me especially on a large screen. It is a a zig-zag from bottom left to top right - almost as if the contrast has changed. I first thought it was RF interference but it continues even if I remove the RF leads. So far I have only used the s-video output from the Sky+ box so I am not sure if it exists on the composite or RGB outputs.
