willscary- I think you missed what I'm trying to do.

Here's what an example. I set up M1 to be the following keystrokes:

AUD, AM/FM

So from any mode on the remote, I can switch to the tuner. So it is taking the Aud button in that case. And I double checked this, because if I hit DVD, and then try AM/FM, doesn't work because the AUD button wasn't hit 1st.

So this morning, I tried to simply program M4 to this:

AUD

But it doesn't work. My only conclusion is that AUD is a *modifer* button. (Sort of like SHIFT on a PC keyboard.)

I just Re-read your post. I'm trying to reprogram the Power button to be AUD.

I've gotten the Power button to take other commands, so it does act exactly like the other macro buttons. Just won't take AUD by itself.

It's a mystery!
