No subs?

I heard a lot about this documentary, and it seem a really enjoyable and funny one. It's an essential source of information and good stories for all the shi-fi fans, but I noticed that the dvd release came out without any embedded subs. And no "fans" subs are available from the net. That's a shame for all the foreigners viewers (like me, as everybody can argue from the bad english) who can't speak english very well.

Well, I think it's strange this lack of captions... I need to learn, I know, but what about hearing-impaired people?
