MPMoviePlayerController strange behavior

MPMoviePlayerController strange behavior

I 've been working on playing a video from a URL using the MPMoviePlayerController object. However when playback return from FullScreen mode, the MPMoviePlayerController black bands will appear at the top and bottom. I tried to solve using AspectFill without any result. In addition , returning the FullScreen Status bar disappears. Greetings. Thanks .. Attach my Custom Renderer code and image app.

[assembly: ExportRenderer(typeof(VideoViewOS), typeof(VideoViewOSRenderer))]
namespace Clazloop.iOS
{
public class VideoViewOSRenderer : ViewRenderer<VideoViewOS, UIView>
{
MPMoviePlayerController _player;
private List _observers = new List ();

    protected override void OnElementChanged (ElementChangedEventArgs<VideoViewOS> e)
    {
        base.OnElementChanged (e);
        if (e.NewElement != null)
        {
            if (base.Control == null)
            {
                _player = new MPMoviePlayerController();
                _player.View.Frame = this.Bounds;
                _player.ScalingMode = MPMovieScalingMode.AspectFill;
                _player.ShouldAutoplay = false;
                base.SetNativeControl(_player.View);
                var center = NSNotificationCenter.DefaultCenter;
                _observers.Add(center.AddObserver((NSString)"UIDeviceOrientationDidChangeNotification", DeviceRotated));
                _observers.Add(center.AddObserver(MPMoviePlayerController.PlaybackStateDidChangeNotification, OnLoadStateChanged));
                _observers.Add(center.AddObserver(MPMoviePlayerController.PlaybackDidFinishNotification, OnPlaybackComplete));
                _observers.Add(center.AddObserver(MPMoviePlayerController.WillExitFullscreenNotification, OnExitFullscreen));
                _observers.Add(center.AddObserver(MPMoviePlayerController.WillEnterFullscreenNotification, OnEnterFullscreen));
                ToggleFullscreen ();
            }
