You can change the audio track back to the original.

Not sure if it remembers your preference, though, so if it doesn't that probably grates.

It doesn't remember my preference. Or rather, it seems to remember me picking a specific language, and then loads the dub in that language next time I click a video. It doesn't remember "don't duh videos".

It does remember it. At least on Firefox/Linux.
