I just replaced my Marantz 5500 with the 990/7125....fantastic sound...much better that I expected. The reviews on the 990 are good and the product is just short of unbelievable. I have encountered a problem with my Optoma EP 758 projector recognizing the signal from my Samsung HD-841 DVD player. At first there was no problem...especially if I turned the 990/7125 and DVD player on first then the projector. But now the screen displays the information "Samsung..." logo and when the DVD is started the screen flickers blue and there is no picture (you can here the audio but no pic). The DVD player is set to 1080 as it is an upconverting player and the DVI connection has been chosen in the DVD setup menu....Any suggestions?
