Video quits after a few minutes of play
When I try to play a video (i.e. my yoga workout) via airplay from my iPad air, it plays for a minute or so and then goes to the swirling asterisk or quits completely. Works well on streaming apps. Thoughts anyone? It's an older Apple TV. I don't know where to start in figuring out the issue. The iOS is up to date on the iPad, don't know about the Apple TV, don't know how to check.
iPad, iOS 10
