Anyone got any idea about this problem? I just took delivery and set up my new Denon 2910 and Paioneer PDP-426SXE. At first look everything is wonderful - very impressed. Then last night I sampled a look at my DVD of Steely Dan in concert 'Two Against Nature', expecting to be joyfully entertained. However, there is a serious picture/sound sync problem with this disc, not seen on watching movies. The 2910 is outputting the signal as progressing 720p via HDMI. Anyone got any ideas whats up?
