I also got the 807 and am trying to configure my attached devices, but I must be doing something wrong or misread the specifications. I have attached my components like this:
TV: HDMI out
PS3: HDMI1 - Input: DVD/BD
PVR: HDMI2 - Input: VCR/DVR
STB: HDMI3 - Input: CBL/SAT
xBox: Composite video and audio to GAME - Input Game
Wii: Component1 and audio to analog DVD/BD - Input DVD/BD
But when both my Wii and PS3 are turned on, I can't switch between them with the remote as they are both mapped to the DVD/BD input. Is it really true that the receiver has 6xHDMI + 2xComponent + 4xS-video inputs, but they need to be mapped to the only five to six selectable inputs: DVD/BD and VCR/DVR and CBL/SAT and Game and Aux (and Port)? I expect I can solve the problem by using the TV/Tape input, but I find it quite sad that I need to "cheat" to find available inputs already. I didn't expect to run out of available port for many years, but now it seems I'm already at it's limit.
I really hope I must be overlooking the obvious as this is a huge limitation as I see it.
