Any sport that's played at professional level usually has a deal done with a broadcaster. They get exclusive rights to it and no one else. Even amateur sports that are just covered for a brief item on the six o clock news, has a tv company involved and they own all rights to the pictures and soundtrack. Recording bits and pieces of it for your own enjoyment to watch later at home is one thing, but making dvd's of it and then flogging them is opening up a lot of trouble for you.
