I was flicking through N-Gamer magazine and I noticed that they had found a Zelda Documentary originally in Japanese translated for the first time in English here are the links (for Download)
Zelda no Video: The History of Zelda Low Quality [.avi] [427 mb]
Zelda no Video: The History of Zelda High Quality [.mp4] [734 mb]
By the looks of the link you could be able to stream these.
If you want to read the gripping story of how they translated it here is the original link
