iphone - MPMoviePlayerController 延迟实际上应该没有

Question

每次我的应用程序更改显示的动画(这是一部循环电影)时，他都会暂停，直到最终开始播放电影。MoviePlayerConntroller 是这样创建的

    self.moviePlayer = [MPMoviePlayerController alloc];
    [moviePlayer initWithContentURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"NewChar" ofType:@"m4v"]] ];
    // remove playerview from our view (no prob is he isnt attached to any)
    [moviePlayer.view removeFromSuperview];
    // tell our playerview the size he has to use
    moviePlayer.view.frame = CGRectMake(0, 0, 320, 430);
    // and add hin to the superview behind everything else
    [self.view insertSubview:moviePlayer.view atIndex:0];
    // no moviecontrolls
    moviePlayer.controlStyle = MPMovieControlStyleNone;
    // looping forever
    moviePlayer.repeatMode= MPMovieRepeatModeOne;
    // let him use his own Audio Session for old devices
    moviePlayer.useApplicationAudioSession= NO;
    // fix the silly black background on iOS 4.3
    moviePlayer.view.backgroundColor = [UIColor clearColor];

实际的电影是这样播放的

[moviePlayer initWithContentURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"Whatever" ofType:@"m4v"]]];
[moviePlayer play];

正如我所说，每次电影更换时，他都会花一段时间来显示它。在较新的设备上还可以，因为它们速度更快，但在 G2 上这有点令人不安。尝试准备播放，但这没有什么区别。

知道我错过了什么吗？

从磁盘加载电影需要时间，并且在旧设备上显然会更慢。视频有多大？
