Thanks for helping. I moved the Xbox to another tested/working AVR input. The behavior is the same: I get a "no signal" on the TV screen until I unhook the game from the input. Boom OSD comes back.
Marantz has confirmed this model AVR does not allow any selectable output scaling.
I meant for you to plug the xBox into input A, plug a blue ray into input B. Switch the AVR to input B and see if the OSD still works. If not, unplug the xBox from input A and test again.
Just figuring out if the xBox itself isn't over powering the HDMI switcher in the AVR.
