iOS - EXC_BAD_ACCESS when executing a segue to MPMoviePlayerViewController - iphone

Question

I am using Storyboard-
I am pretty new to this-
I'm getting a EXC_BAD_ACCESS (code=2, address = 0x4) error when I click a button pointing to a MPMoviePlayerViewController.
To give you an idea of what I've got so far: I have several different ViewControllers all under the same ViewController.h/m class with navigation controlled by a NavigationController. I started with a NavController and single ViewController and have been linking new ViewControllers with the simple CTRL-Click button-to-new-ViewController. I added a new ViewController; changed it's class to MPMoviePlayerViewController in the Custom Class section of the Identity Inspector, but I keep getting this error when I click on the button to begin the transition.
Here's my ViewController.h code if it's relevant:
- (IBAction)postToTwitter:(id)sender {
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]) {
SLComposeViewController *tweetSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
[tweetSheet setInitialText:#"Check this out!"];
[self presentViewController:tweetSheet animated:YES completion:nil];
}
}
- (IBAction)postToFacebook:(id)sender {
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
[controller setInitialText:#"Posted from IOS App Test -- It works!"];
[self presentViewController:controller animated:YES completion:Nil];
}
}
- (IBAction)playVideo1:(id)sender {
NSURL * url = [[NSURL alloc]initWithString:#"link omitted"];
//create our moviePlayer
moviePlayer = [[MPMoviePlayerController alloc]initWithContentURL:url];
[self.view addSubview:moviePlayer.view];
//Some additional customization
moviePlayer.fullscreen = YES;
moviePlayer.allowsAirPlay = YES;
moviePlayer.shouldAutoplay = NO;
moviePlayer.controlStyle = MPMovieControlStyleDefault;
}
