I think, typically, when a DVD with copy-protection is manufactured,
it is sent on DLT tape or a special "DVD for Authoring" disc which
contains the unencrypted movie but also an extra area with encryption
data needed by the disc manufacturer who can press the real, encrypted
DVDs. In other words you can't burn your own CSS-encrypted DVD at
home. :)
