MPMoviePlayerViewController can not play mp4 file

Question

I'm working on a test application that will run an mp4 file from internet. code is :

-(IBAction)playRemoteVideo
{

    NSString *mp4File = @"http://archive.org/download/Pbtestfilemp4videotestmp4/video_test_512kb.mp4";

    MPMoviePlayerViewController *playerController = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:mp4File]];
    [self presentMoviePlayerViewControllerAnimated:playerController];
    playerController.moviePlayer.movieSourceType=MPMovieSourceTypeStreaming;

    [playerController.moviePlayer play];
    [playerController release];
    playerController=nil;
}

When I run the application and played the video the player tries to load the video for a while but after I got this exception on console

2012-04-18 22:45:11.309 VideoPlayer[891:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'An AVPlayerItem can occupy only one position in a player's queue at a time.'

terminate called throwing an exception(gdb)

If I execute the same code with an m3u8 file , for instance;

http://devimages.apple.com/iphone/samples/bipbop/gear1/prog_index.m3u8

I can get the video running but same does not work for mp4 file.

Do you have any idea why I got this exception and what's wrong with my code?

I run the application on Iphone simulator and I have XCode 4.2 Best Regards Tugrul

Set the movie player's control style like so.

[self.mPlayer.moviePlayer setControlStyle:MPMovieControlStyleDefault];

Also, local files have the MPMovieSourceTypeFile, not MPMovieSourceTypeStreaming property set.
