Handheld.PlayFullScreenMovie only plays sound, but no video

We had the same problem on iOS. Playing the movies from a coroutine and inserting a yield to wait for a second solved the problem.

 IEnumerator PlayMovies() {
     iPhoneUtils.PlayMovie("Movie1.mov", Color.black, iPhoneMovieControlMode.CancelOnTouch);
     yield return new WaitForSeconds(1.0f);
     iPhoneUtils.PlayMovie("Movie2.mov", Color.black, iPhoneMovieControlMode.CancelOnTouch);
 }
