are you using an iPad as your control surface for the theater or a Crestron touchpanel or remote?I've had Crestron controls in my home theatre for over a decade, but it's been a big hassle getting it reprogrammed for new gear.
Apple for example doesn't have anything on Crestron as far as tightly controlling their ecosystem.
Or at least, that used to be the case. I haven't upgraded anything in a couple of years.
