i dont think is the receiver either

i have the same receiver ,,, i did follow the set up menu and also assigned outputs to cable box ( hdmi #2 and Hd_dvd hdmi #1)and from my Avr output to my Hd tv input which only works on Hdmi #3 on the tv so you can also check on your Tv and make sure it works on all inputs, also try connecting the devices straight to your tv and see if they work properly ,,,i know it took me over 2 hrs to get everything set up the 1 st time and then i disconnected everything and did it again ,,,so make sure you start on your manual step 1 and follow it step by step,,, good luck and be patience,,,, Wc
