So after researching, I get it won't let me put it delays in certain spots. I don't think it would help anyway. But here's the weird thing, I got it working when I am doing the PS4 activity to the projector.
Here's how that is set up. Because of the nature of the menu system, to automate the procedure for putting the video out to the projector instead of the TV, I have to have it press AvAdjust on the receiver, then a series of arrows to navigate the menu, and switch the output to sub, for the projector. But because it's an option menu, not a setting I can set it to, I have to have it set it back to main in the power of procedure. Anyway, not sure of that makes sense, but I have it working.
And for some reason, when I run the ps4 activity outputted to the projector, then the power off activity works and powers off the receiver.
But when I run the PS4 activity outputted to the TV (no funky menu navigation), the power off activity does not power off the receiver.
Not sure if any of that had anything to do with it or not. But thought I'd mention it. It really bugs me I can't figure out how to get it to power off the receiver when using the PS4.
