MPMoviePlayerViewController can not play mp4 file

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
