During play, if i swipe down on the apple remote to expose the Subtitles & Audio Panel and dismiss this panel, the playback track at the bottom of the scree remains on. Only way to get rid of it is to exit the movie and re-Play it.
Welll i had this problem kind of, specially after installing the app. So i had to stop the app and re lunch it.
to stop app click on the home screen the home button two times and there on is like the phone, slide up what ever app you wanna close.
