Gravity iTunes extras won't play
I bought this film from the store last week and I can't get the videos in the itunes extras to play. Nothing happens when I click on them, is this happening with anybody else or is there something I'm missing? I've tried deleting the movie and the extras file and redownloading but the same thing keeps happening. Other movies' itunes extras work fine.
