Am I able to use Apple TV anywhere?
I want to plug my Apple TV to my sons classroom projector to watch an iTunes movie. If they have wifi is this possible?
If the movie is under Movies or TV Shows section in Apple TV, you would be able to stream it anywhere you have an internet connection.
If you have a movie under Computers section, you will need to bring a computer and stream a movie via AirPlay
Use AirPlay to stream content from iTunes on your computer - Apple Support
