Frink, the audio is really messed up--at least for the first bit, I haven't yet watched past 1 minute. All I can hear is the drums, which continue throughout the whole minute. All the little singing people pop up and sing, but silently, while the drums beat on and on and on. It might just be me, but I'm pretty sure it isn't.
EDIT: The channel with the dialogue is completely missing. All other sounds appear to be present.
