Just received the Pioneer Elite VSX-92TXH and have it hooked up. It has 3 HDMI inputs and 1 output (to HC1500 projector). So far, I have two HDMI devices. The Samsung HD tuner works fine. I get both audio and video without any problems.
The Denon 3910 is another story. When selecting DVD and the correct HDMI input, I get NO audio or video output. I finally figured out after a bunch of tweaking with it that if I don't have the projector turned on or I have the projector set to a different input (i.e. s-video) rather than HDMI, I get audio just fine from the Denon.
I tried changing the HDMI settings on the Denon between 720p and 1080i as well as from RGB to YCBr setting. No luck.
When the Denon is connected directly via HDMI to the projector without the amp in the middle, I get video signal no problem.
Any ideas are greatly appreciated.
