As I said in a post on the close-up section, the "release" has you giving your ideas, video, pics, whatever, to the production company without compensation, other than a "special thanks" in the credits. How generous!

They begin by trying to get material from everyone they can for free. A demo video (without a release) is one thing....ideas and full acts are something else. Obviously, they think there are a large number of magicians so anxious to be on TV that they'll give their stuff away for the "exposure."
They're probably right.
