True they do ask for the right but the important thing to remember is in most cases with the CBC it is a non-exclusive licenses. This means that while CBC owns the piece you have not given up your ownership. So while CBC has the right to rebroadcast, or put it up on the net you still hold the right to broadcast it elsewhere. But then again besides Zed, you will find it just about imposable to find somebodywho will both broadcast and pay to broadcast your work if you happen to make independent short videos. See it from CBC's perspective, they are investing in the piece by broadcasting it and paying you for it so they don't want to risk you just deciding you do not want them to have it anymore and pulling the rug out from under them. Also everything is negotiable, look at the Revolution OS page on Zed, you can't watch the film like other Zed content probably cause that is what the director negotiated.
