Intro video corrupt

Firefox says: “Video can’t be played because the file is corrupt.”
Chrome plays the audio, but no video.

The “small” video works fine.

I also had problems watching it and finally decided to download it instead of watching it within my browser(s). This worked a bit better but I still had interrupted sound effects and the video stopped at minute 5:30 or so.
