You might want to locally host the Wiinja videos. They both say "This video is no longer available"i wanted to watch the videos when i finally got my soldering iron, and now pfft... can't watch it anymore.
As it would transpire I pulled the flv files from youtube (I was going to use them to test video on my new machine), the second is a bit pixelated in the borders about 4 and a half minutes in but it is good otherwise.
I can upload if you want.
