Am I the only one having problems getting purchased movies to play via AirPlay? I've bought a bunch of TV programmes for teaching and I couldn't get them to play on 10.13.1 (I just got beachball and no video). I filed a bug report with Apple. Now in 10.13.2 it is even worse. My main display goes grey. My pointer disappears and there's glitching as I move the invisible pointer around on my extended display (on the the Apple TV 4K). And now I get a warning about "The selected film won’t play on one of your connected displays." due to copyright reasons. These are all shows I purchased from Apple.
