Doesn't the authority of the copyright owner to descramble, decrypt, or otherwise bypass a technological measure extend to those who own a legal copy of the copyrighted work? That is, the rightsholder implicitly transfers the authority to decrypt the work when he issues a license to view the decrypted material, even if the medium of transfer stores the work in an encrypted format. Under this interpretation, the authority would extend to viewing the material on any platform or player, but it wouldn't extend to saving a permanently decrypted copy (as you had a license to view the decrypted material, but not to keep a permanent decrypted copy) as in a rip of the DVD to one's hard drive.
