  • Video:
  • Audio Description:
  • English Dub:
  • Spanish Dub:

There are one video and three audio files that are played in parallel. You can watch how they go out of sync over time unless you pause, which re-syncs.

Note: The demo works best in Firefox version >= 3.5, but also in Chrome. It doesn't work (well) in Chrome or Safari. It will not work in IE.
