This is something that's been an issue for many of us. The solution that works for me (some of the time) is to turn the subtitles on and make them US: English. With some movies it will turn off the subtitles altogether, as weird as it sounds. After the movie plays for a while I can sometimes turn the subtitles off and all will be fine. It's a problem with the movie itself, not with your device. Apple is aware, from what I read online, but they don't have a fix or an explanation for it.
