What would you do if you had few thousands of full length DVD videos?

Make a searchable and user editable front-end database with titles, covers, screenshots, performer names and previews (for the public.) As for the full length movies, I'd probably have them streamable to premium members. You're sitting on a gold mine, good luck. :)

do you have all the licenses and distributions rights to resell it ?
