iTunes movies out of synch
I have an Apple TV 4 and I find that any of the movies I get from iTunes (rent or buy) have the audio half a second behind the video so it's out of synch. I don't see the same problem when using Netflix or BBC iPlayer. Has anyone got any ideas? Thanks in advance for any help!
