by the way here's how i use mpmovieplayercontroller for streaming :

NSURL *url = [NSURL URLWithString:videoUrl];
moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];
[moviePlayer setControlStyle:MPMovieControlStyleDefault];
moviePlayer.scalingMode = MPMovieScalingModeAspectFit;
CGRect frame;
if(self.interfaceOrientation ==UIInterfaceOrientationPortrait)
    frame = CGRectMake(20, 69, 280, 170);
else if(self.interfaceOrientation ==UIInterfaceOrientationLandscapeLeft || self.interfaceOrientation ==UIInterfaceOrientationLandscapeRight)
    frame = CGRectMake(20, 61, 210, 170);
[moviePlayer.view setFrame:frame];  // player's frame must match parent's
[self.view addSubview: moviePlayer.view];
[self.view bringSubviewToFront:moviePlayer.view];

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(moviePlayBackDidFinish:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:moviePlayer];

[moviePlayer prepareToPlay];
[moviePlayer play];

and then here's the delegate method :

- (void) moviePlayBackDidFinish:(NSNotification*)notification {
       MPMoviePlayerController *player = [notification object];
       [[NSNotificationCenter defaultCenter] 
            removeObserver:self
            name:MPMoviePlayerPlaybackDidFinishNotification
            object:player];

       if ([player respondsToSelector:@selector(setFullscreen:animated:)]){
          //self.navigationController.navigationBarHidden = YES;
          [player.view removeFromSuperview];
       }
}

hope this will help you..

As far as I know you have 2 options:

1) First download the file and play it locally. Like this:

   NSString *url = [[NSBundle mainBundle] pathForResource:@"cwtvideo" ofType:@"mp4"];
   MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:url]];

2) Use the HTTP streaming protocol. As far as I know HTTP streaming is the only streaming protocol known by the MPMoviePlayerController.

Hope this helps.

Cheers!
