I have a MPMoviewPlayerViewController embedded into an UIView object. When I start the player in the embedded mode everything works fine and as expected. If the user then taps onto the fullscreen toggle (or if I change to fullscreen programmatically using setFullscreen:animated) the player goes fullscreen, the movie plays for another second and after that the screen goes black with only a "Loading..." message.
This behavior only appears using iOS 6 (also iPad 6.0 Simulator), on devices running iOS 5 everything works as intended.
The movie source is a local file from the app bundle.
Upon playing & entering fullscreen the debug output is as follows:

Has somebody an idea why the player stops working?
Edit: Added an example project on github
I solved it by myself. As I add the Movie Player as a subview to a container view I don't need to use the actual view controller created with the MPMoviePlayerViewController which is intended to be used to present it modally or in some other vc hierarchy.
For the single purpose of having a Movie Player view that can be added to some other view as a subview the MPMoviePlayerController's view property is sufficient.
Until iOS 6 both worked but iOS 6 seems to differ in terms of ressource management/lifetime.
The example project is updated with working code.
