IPhone memory leak from AudioToolbox when using MPMoviePlayerViewController iOS 4.2

I use the following code (inside the view controller in the tab bar application) to play the video downloaded from the main package after the user selects a row in the table.

- (void)loadMoviePlayer:(NSString*)moviePath
{
    NSURL* fileURL    =   [[NSURL alloc] initFileURLWithPath:moviePath];

    MPMoviePlayerViewController* player = [[MPMoviePlayerViewController alloc] initWithContentURL:fileURL];
    [fileURL release];

    [self presentMoviePlayerViewControllerAnimated:player];
    [player release];
}

The application creates and runs without any obvious problems in the simulator (I have not tested it on the device yet), but when I run it through the tools, a memory leak occurs during video playback. Tools distinguish AudioToolbox as the “Responsible Library” and SimAggregateDevice::SimAggregateDevice(_CFString const*, _CFString const*, long&) and

APComponent::CreateDispatchTable(AudioComponentPluginInterface*, unsigned long)

like "Responsible Personnel (s)".

Any light you can shed on this will be greatly appreciated! Thank.
