i have seen a lot of threads on this set but this is my 1st ever post. i have a pioneer 444 dvd player going into AV4 via a QED scart (picture only) when i play dvd's during the intro or the opening credits where there is a black background i get white horizontal lines flickering. i swapped to the AV1 last night and the problem was reduced but i can still see it very faintly. i have lowered the contrast considerably. it is nowhere near as bad as it was but is very slightly visible. now that Sky has been switched to AV4 (also via fully wired QED scart) i am convinced the picture isn't as good. any hints/tips on getting the best out of each component?
