I dunno man, once a show is in the public domain it\'s fair game. I\'ve never heard of a cease-and-decist order on trading a show because someone later on decided they wanted to make a profit on it. If taping was allowed then nobody can possibly "own the rights" to the show. If he owned the rights then he could sue tapers, but he can\'t sue the the tapers because it was legal at the time. (The tapers are protected by Ex Post Facto.) For example, Phish has made a lot of money selling LivePhish discs and live downloads of old shows, while fans are still allowed to trade these shows. Phish competes by offering great soundbaord quality and packaging. If your boy wants to go back and sell copies of the show that\'s fine, he can do that, and he will have to offer something more than the average trader gets. I\'m sorry, but you can\'t order people to stop trading a show that was legally taped, that is totally unprecedented.
