Handheld.PlayFullScreenMovie not working on iOS9

Hi, I'm currently having issues with the movieplayer on iOS9 in combination with XCode 7.0.1 (OS X 10.10.5). The video is placed on our server, but doesn't play, all I'm seeing is a black movieplayer with controls, but no movie and timings displayed like --/--. This does work on iOS 7 and 8, and it does also work on iOS 9 when building with XCode 6.2 (OS X 10.9.5) I'm working with Unity 4.6.5, and have tested it also with 4.6.7 Handheld.PlayFullScreenMovie(url, Color.black, FullScreenMovieControlMode.Full, FullScreenMovieScalingMode.AspectFit);
