Quicktime offers a feature called “Kiosk Mode” that removes the rightmost menu arrow on the QuickTime player which also removes the “Save as” functionality. Kiosk mode is an option that can be set for a QuickTime movie, so that even users who have QuickTime Professional cannot copy the source of a movie. To enable kiosk mode, add a param tag to your object tag, named “kioskmode” with a value of “true”. Also add kioskmode=”true” to the embed tag.
