Actually, there is a rather nasty copy protection scheme used in many
DVDs... I'm halfway being sarcastic about this, but somewhat serious:
Nasty broken telecine. Discs which mix hard and soft telecine at
random, or use very weird telecine patterns which are difficult to
detect. Whether this is intended as a copy protection mechanism is a
question i leave to the conspiracy theorists, but in practice, it
makes it hard as hell to rip a working copy of certain DVDs... See
samurix_detc.avi for a horrible example.
