Thanks for your input! Let me answer some questions.
Sorry, perhaps not descriptive enough. Both the TV and the HT receiver allow control of other HDMI devices. So by enabling the features so that the TV controls the HT receiver, all I have to do to turn both on or off is to turn the TV on or off. Another cool thing is the TV passes the volume control to the HT receiver. Again, all I do is press the TV volume up or down and the HT receiver does the actual adjustment. This occurs using only the TV remote on TV, not programming it to control the HT receiver. Makes sense? This process works flawlessly until the 722 is added to the setup.
The thing is, until the 722 is added to the setup, the Sony controls the Onkyo without issue. I have also used 3 different HDMI cables by two manufactures (all HDMI 1.3a compliant) and this power/volume connection always fails once the HDMI from the 722 is plugged in.
The Onkyo uses assignable HDMI (3 inputs and you go into menus and tell the receiver which input is what device). I have moved around the assignments, thinking the Onkyo could be confused by me telling it the 722 was TV/SAT. So I moved the 722 to DVD, GAME, and AUX and the power/volume connection still did not work.
This could all be a minor inconvenience, except the Onkyo has distinct power on & standby codes, so the Dish remote can only turn it on, not off. Guess it's time for a Logitech... I just hate that because everything was working when I had an older receiver.
