Otaku -- one translation in Japanese has this as a form of the word "You"..... But since this is Anime it would not be that simple. In Japan it really indicates someone who is a megafan of something or other, such as computers, video games, martial arts, etc. When used in the U.S. it specifically, and only [mostly], applies to a megafan of Japanese animation.
No -- usually translated as "the"
Video -- Video
So, if you put it all together, Otaku No Video means Your Video, or A Video for Mega Anime fans.
[A complete aside here: Or, as Thomas Baetzler (email@example.com) mentioned to me 'The Otaku's Video'. However, that does not really tell you what an Otaku is. One might want to visit Volker Grassmuck's page on the subject.]
It really is a fake documentary [of sorts] about the Anime industry, and specifically the Gainax studio.
A number of years ago, the members of Monty Python and some of the current cast of Saturday Night Live made a fake documentary about the Beetles. It was called the Rutles. Otaku No Video is similar.
This is a rather cute, but somewhat odd, set of movies. There are a huge number of in-jokes and references, of which, I caught a very very few. I am very happy for the video liners.
