Of course if its Greenlights own footage but they were talking about members of the public taking video and sticking it up on the web.
What I said still stands here`s a test.

Loads of video clips that I took last year
Best ones are of Big John in the pits and he is asked by another rider where are you picking it up.

I own the Copyright maybe I might let Greenlight use it all depends.
Oh I pay to have it on the web simply cos I love the TT and like to share.
