Here is a link to a 3 part 'documentary', length is 21min, language is english but overdubbed with german.
http://de.movies.yahoo.com/blog/article/22851/exklusives-star-wars-special.html
it is copyright 2011 as it features the blu ray menues and shows clips from them.
please post here if you find a higher quality version or if you find an english only version.
It's a shame that there are so many gigabyte left free on those bonus discs! But no 'From Star Wars to Jedi', no stuff from the dvd releases ported over.
