This should clarify the debate on videos.

"Home Use Only" videocassettes
If an educational institution purchases a copy of a videocassette bearing the warning label "For Home Use Only," the 1976 copyright law allows use of the tape for face-to-face instruction with students if the tape is incorporated as part of systematic teaching activities. That is, teachers are not permitted to use these tapes just to entertain students. Under the Section 110(1) performance exemption, copyright law allows educators to use such tapes only for instructional purposes unless a specific agreement was made at the time of purchase.
The use of rental videocassettes bearing the "Home Use Only" warning label falls generally under the same Section 110(1) exemption for education, depending how the video is rented. If the school or an individual rents a video, but has signed a rental agreement or a membership card that states that the use of the videos is restricted to "Home Use Only," this rental agreement, or contract, might override the special exemption given to educators. To be on the safe side, make sure schools do not use videos that have been rented under a signed agreement that restricts use solely to "home use."
