Play movies on Apple TV from iTunes on PC
If you have an Apple TV, you can use it to watch movies from your computer on your TV. You might need to convert some movies to work with Apple TV. Any video that plays on iPhone, iPad, or iPod is compatible with Apple TV.
In the iTunes app on your PC, choose Movies from the pop-up menu at the top left, then click Library.
If you don’t see Movies in the pop-up menu, you need to use the Apple TV app you installed on your device. See the Apple TV User Guide for Windows for more details.
Select the movie, then choose File > Convert > Create iPad or Apple TV Version.
Converting a movie for Apple TV can take from several minutes to several hours, depending on your computer and on the length and content of the movie.
The original movie file remains in your iTunes library.
