We obtain a release from the speaker for member use only. I think it's incorporated into the original contract. The images they are projecting are theirs(or at least they darn well better be) and are covered under the same release. It's a huge benefit for members like me and my wife because we are working continuously throughout the conferences. We love helping out and by being able to view the presentations later it frees us up to do many jobs, all of which we love.
