MPMoviePlayerViewController Generating lots of errors

我正在尝试在iOS6上使用MPMovieViewController播放电影，并在我的控制台中收到以下消息：

当我尝试从此网址播放时：http://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4它有效。当我下载这个确切的文件并将其放在我们的服务器http://loadoutnews.co/hat/default/download/post.videoios.afa1cc6b18aa0e03.6269675f6275636b5f62756e6e792e6d7034.mp4上时，它无法正常工作并给我这些错误。我确保URL是有效的，如果需要也可以正确地进行％转义。这是我播放视频的代码：

//video 5
        NSDictionary *dict = [list objectAtIndex:indexPath.row];
        NSString *escapedValue = [NSString stringWithFormat:@"%@%@",@"http://loadoutnews.co/hat/default/download/",[dict objectForKey:@"videoios"]];
        escapedValue = [escapedValue stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
        MPMoviePlayerViewController *player = [[MPMoviePlayerViewController alloc] initWithContentURL:[NSURL URLWithString:escapedValue]];
        [player.view setBounds:self.view.bounds];
        [self presentModalViewController:player animated:YES];
        //I have tried it with and without this line below
        [player.moviePlayer play];
        [player release];

我觉得很奇怪它确实在给定的初始链接上播放视频，但在我们的服务器上却没有。如果你转到我发送的链接，视频文件是有效的，是相同的...我不明白为什么它不起作用。谢谢你的帮助！
