MPMoviePlayerController is still leaking

Question

I release MPMoviePlayerController, but memory allocation and live objects are still higher than before allocating the object. However, if I redistribute the object, it no longer flows. My application actually uses a lot of media files, and the memory consumption is high. I would like to completely free up unnecessary memory in order to avoid memory warnings.

Movie Release:

        player.initialPlaybackTime = -1;
        [player.view removeFromSuperview];
        [player stop];
        [player release];

Video player placement:

    NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"video0_hd.mov" ofType:nil]];
    player = [[MPMoviePlayerController alloc] initWithContentURL:url];
    player.view.frame = placeholder.frame;
    [self.view addSubview:player.view];
    [player play];

However, on my iPhone (with 20 MB video), it allocated only 900 KB of shared memory for the application, with no noticeable changes when starting / stopping / releasing the video. It always remained approximately 900 kb for 10 times when I tested it (start / stop / release).

It looks like the next time you won’t be able to trust the simulator.

Code I tested:

NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"SomeMovieFile" ofType:@"mp4"]];

MPMoviePlayerController *newPlayer = [[MPMoviePlayerController alloc] initWithContentURL:url];

self.player = newPlayer;  
[newPlayer release];

[self.view addSubview:player.view];  // for my example, I didn't set the frame location, but no difference that would do
[player play];

Then in another button I stopped it and released the player:

[player.view removeFromSuperview];    
player.initialPlaybackTime = -1;
[player stop];
self.player = nil;  // this is just a habit of mine.. calling stop should unload the buffers though
[player release];
