A bit of a mis-observation on my part. Sorry. If you are going into component to output over HDMI and press the secret button sequence and then go back into your selected input (Cbl/SAt) the display will show cbl/sat, then when the AVR actually switches, then the hidden menu reappears. I was confused on this because of the time delay. After this happens however, the hidden menu persists, allowing you to make changes until you exit via the set up button.
I guess the obvious question then would be, what if you don't access the hidden menu first. My experiment say that you get the processing when component toi HDMI regardless.
