Apple TV out of sync
Hi guys, my Apple TV has been fine but around Christmas time with no warning everything (literally everything) except trailers had a delay in the audio hence talking in downloaded movies or on netflix is out of sync with the picture, despite the fact that they all worked fine before this random glitch. This hasn't happened on any of my other devices and I have tried restarting the Apple TV and tried restoring to factory settings both to no avail, please can someone help thanks.
