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. :)
