For what its worth, Sexpert has a decent point that I think does justify discussion... sometimes its appropriate for a director to put their name on a project, other times, its not as necessary, justified, or fitting.
However, sometimes one particular person IS in fact responsible for nearly every aspect of a project, and it REALLY is their deal, and theirs alone... liken it to a work of written fiction- would an author not use their own name? There are also situations where a director or producer's name is used as a selling point...
I will point out, however, that many snowboard filmmakers have put their names on projects in the past, even as bluntly as declaring "a film by ___________." Do note that many of the current major productions are in fact NOT directed by one person, and rather the project is a cooperative group effort. Also, note that many of the larger snowboard production companies have been around so long that they've had a few different people take the helm of some of their different projects- that, and they only need to rely on the recognition factor of the name of the company itself, rather then a director/producer.
My 2 cents.
