MPMoviePlayerController doesnot play the video its full length - iphone

Question

I am using the MPMoviePlayerController to open a video file.The video runs fine.But suppose if the video file is 10 sec ,with 1 sec remaining the video stops.Is that its natural way of playing or should we specify something.The follow is the code used
NSURL *fileURL = [NSURL URLWithString:location];
self.moviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(moviePlaybackComplete:)
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.moviePlayerController];
self.moviePlayerController.controlStyle = MPMovieControlStyleFullscreen;
self.moviePlayerController.movieSourceType = MPMovieSourceTypeFile;
[self.moviePlayerController prepareToPlay];
[self.moviePlayerController.view setFrame: CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)];
[self.view addSubview:self.moviePlayerController.view];
- (void)moviePlaybackComplete:(NSNotification *)notification {
NSNumber *finishReason = [[notification userInfo] objectForKey:MPMoviePlayerPlaybackDidFinishReasonUserInfoKey];
if ([finishReason intValue] != MPMovieFinishReasonPlaybackEnded) {
self.moviePlayerController = [notification object];
self.moviePlayerController.view.hidden = YES;
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification
object:self.moviePlayerController];
[self.moviePlayerController.view removeFromSuperview];
[self.moviePlayerController release];
}
[self dismissViewControllerAnimated:YES completion:nil];
}
