Tarun,

Try running a set of component video cables directly from the DVD players to your projector to eliminate the possibility that an intermittent video cable inside the wall is being vibrated by the EP500. We had a couple of other cases where the EP500 was vibrating a video cable to the TV display, causing a visible "jitter" of the picture. The video cable hot or ground lead were at fault, and replacing the cable cured the problem.
