I am currently connecting the seleco to a non-progressive pioneer 656a dvd player using s-video. The seleco has an internal line doubler which is always activated. I wonder if anybody has advice for getting more out of the projector? Should I connect to the projector using its RGBHV BNC inputs? I assume that I need to replace my dvd player if I do this as it only has RGB component ouputs....is this correct? Would a scaler offer any improvement, and if so which should I be considering?
