I've been waiting to sort out my long running Denon DVD-A1 prog scan issue when used in conjunction with my Sim2, but 2 nights ago, the projector went mad and projects a wildly jittering image via component and s-video inputs. I can barely make out what is happening on screen and this applies to all inputs other than "graphics rgb" which is connected to my PC. The flicker seems to be mainly horizontal and in full colour. Tried fiddling with all the cables to no avail. Signals are being routed through a Denon AVC A1SR. Any ideas?
