For example, I set up some systems with a watch catv source button on the home page and the macro has the correct surround mode needed. I then have a cable music channel source button with a different surround mode in macro. Same goes for sat tv/music. You could do the same thing with appletv so long as you have surround mode codes for the processor you are using. You may also just create a processor page with surround modes accessed by a button on the apple page then maybe the home button on the proccessor page is linked to previous/or appleTv to get you back to appletv page. Hope this helps
