I’d like to use some of those commands to have a script be able change the receiver’s video mode (for example, between “movie” and “game”).
What is the recommended way to do something like this?
a) add a subset of commands to the current denon component?
b) create a new denon x2000 (denon protocol E400?) component?
c) write my own custom component with the desired commands?
d) other?
I have an AVR-X4200W so I’m in the exact same boat as you. I have it on my list of things to do to dig into it and figure out what more I can do. Have you made any progress?
