Since the video is at 46664.com, the only reason I can think of as to why Brian doesn't want the video traded (if he doesn't) is that he wants people to go to the 46664 site to view it, hoping people will make a donation while they're there.
Of course, the TV broadcasts had the site address at the bottom of the screen, so personally I'd think trading the videos would advertise the site even more. But maybe his opinion is different.
Or this could be totally wrong...anyway that's my current theory :)
