Mendel.. no offense meant but you ask a lot of really basic questions that you should try to answer on your own.... via the use of your friends, magazines, interviews, google, ex;erience, etc...
the "producer" and the "guy who makes the video" i mean.. that is crazy stuff.. its a legit question and all, but from the stuff you ask ... seriously.... use the goog or your MIND before you ask ... just my 2 cents.
