Непонятные ошибки при использовании MPMoviePlayerViewController

Кто-нибудь знает, что означают эти ошибки? Я получаю это, когда нажимаю кнопку для воспроизведения видео (загрузка через Интернет по запросу).

Моя проблема заключается в том, что мое видео воспроизводится без звука. Фактически, полоса громкости звука полностью исчезает при загрузке.

У меня такое чувство, что это как-то связано с этими ошибками, хех.
