Abstract
A recording apparatus records movie content onto a DVD. The movie content is encrypted using a different encryption method depending on whether the DVD is intended for consumer use or industrial use. If the DVD is for consumer use, a VIDEO_TS directory is created on the DVD, and the encrypted movie content is recorded in the VIDEO_TS directory. If the DVD is for industrial use, a VIDEO_TS directory and an EWCPS_TS directory are created on the DVD, and the encrypted movie content and message data are recorded respectively in the EWCPS_TS directory and the VIDEO_TS directory. The message data indicates that the movie content cannot be played back by consumer DVD players.
