Possible. I haven't programmed a macro for this yet on my Universal Remote but I'll try reversing the order as I am turning the player on first prior to changing inputs because it takes a bit to boot up. Therefore there is a good chance your suggestion is sound, excuse the pun.

An oddity that I forgot to mention is that I do get 5.1 channels showing up on both the input and output visual displays.

With great power comes Awesome irresponsibility.
