I'm having some big issues playing back iTunes-purchased movies on my Mac (2013 Macbook Pro) and was wondering if anyone else was having similar issues. I have a movie that I purchased through the iTunes Store, and whenever I try to play it, the video feed will briefly pause while the audio feed continues, and then the video feed will play super fast to catch up with the audio feed. This process repeats itself constantly and makes watching movies unbearable. I'm not having this issue watching a movie on my Apple TV or my iOS devices...it's just iTunes, apparently. This occurs when I stream movies from the cloud as well as when I download them and try to play them back locally. I'm about to lose my mind...if anyone has any suggestions I'd love to hear them!
