Hi I have just bought a Ae500 projector, my first and I must say I and very pleased with its preformance. However I have noticed one small problem during a DVD film I occasionally (1 or 2 times) get a flicker in the picture, it only last a few frames. could this be a problem with my projector or with the DVD player a pioneer dvr-3100 connected with a RGB Scart cable. - anyone any ideas ? Plus I don't think I have any dead pixels but what is the best way to check. Thanks for you help John.
