Медленный звук в ручнике

Я пытался конвертировать видео H264 до разрешения iPod, чтобы можно было смотреть на моем Palm Pre. Оказывается, что хотя видео конвертируется очень хорошо, звуковая дорожка, похоже, сильно замедлена. Я проверил это с 0.9.3 и svn2907 с похожими результатами.

Оглядываясь вокруг, кажется, что, хотя есть подобные сообщения, не было никаких решений. FWIW, это на Snow Leopard, работающем 10.6.1.

Вывод следующий:
