Play(Stream) Videos in MPMoviePlayerController from a URL ??

Question

i am trying to play a video from a Url with help of MPMovieplayer which loads it in the Quicktime player while i want the video to play in my application only(no background mode)?? how can i achieve that?? will playing the video in a UIWebview instead of MPMoviePlayer work??

Also when QuickTime Player loads only Audio plays and no video is displayed?? i am using the following code

NSString *videoFilepath = @"http://www.migital.com/Hemant/2.3gp";

NSURL *videoURL = [NSURL URLWithString:videoFilepath ];

MPMoviePlayerViewController *movie = [[MPMoviePlayerViewController alloc] initWithContentURL:videoURL];

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(playbackFinishedCallback:)
                                             name:MPMoviePlayerPlaybackDidFinishNotification
                                           object:movie];

[self presentMoviePlayerViewControllerAnimated:movie];
