iPad Movie Player Problem

Question

I am playing mp4 files in iPad using MPMoviePlayerController. I have a view connected in IB to play the video files. The problem is that if one of the files is audio-only, it plays fine, but then videos that play after the audio file do not show the play/pause/seek controls.

I am doing this to initialize the view:

    self.theMovie = [[MPMoviePlayerController alloc] init];
 [self.viewForMovie addSubview:theMovie.view];

Has anyone seen this behavior or have an idea how I can get the video controls to reappear?

Thank you!
