I only have a up convert DVD player. The Blue-ray HDMI Port is still open. When I used the DVD HDMI port as the input from the DVR, I was able to have the surround sound work, but on a limited basis. On certain programs and commericals, the center channel would drop out, just having limited audio from the front speakers. Also the display on the AVR said DVD player. When switched to the TV display on the AVR no TV display or audio. The AVR doe not have a direct HDMI in port for the TV.

Hope this helps in trying to come up with a proper cabling configuration.

Thanks for the help.
