I have just got a BenQ PE8700 projector which works very well except for the fact that there is a delay with the image it projects. I am using an S-video cable from the dvd player to the projector and a surround sound system is connected to the surround system. The picture and sound are always out of sync by about 1/10th of a second which doesn't sound much but is really unwatchable. When I have the TV and projector are both showing a dvd playing at the same time, it is clear to see that the projector image is trailing behind. The TV and sound are always in sync which I think tells me that the surround sound is OK and there is something wrong with the projector or how it is rigged up. i've tried every different settings with the dvd and projector but it never gets any better. Does anyone know why there is a slight picture delay?
