What is this symbol on the Remote App screen?
I'm using the latest beta version of iTunes. When using the Remote App, there is a symbol on the lower part of the GUI alongside the Genius symbol. It looks like a TV screen with a swirl in the centre. I can highlight it and it goes blue like AirPlay does when in use, but there is no obvious change to any output either via iTunes or when I use Apple TV. I haven't been able to find any help via the Apple site. Can anyone out there enlighten me please?
