Speaker 1: Welcome to brain Stuff from house stuff works dot com
Speaker 1: where smart happens. I am Marshall Brain with today's question
Speaker 1: why can I play some DVD movies but not others
Speaker 1: on my computers? DVD ROM player DVD movies have region codes,
Speaker 1: and they typically only play on a player or DVD
Speaker 1: ROM drives sold in the country where the DVD movie
Speaker 1: was sold. The actual region code is in one byte
Speaker 1: on the DVD. The DVD player or drive has a
Speaker 1: region code and its firmware. Personal computer DVD ROM players
Speaker 1: often have the code either in their software or the
Speaker 1: MPEG two dcoder. The two codes must match for the
Speaker 1: player or drive to play the movie. The code is
Speaker 1: also printed on the back of the DVD package, superimposed
Speaker 1: on a small image of the lobe. Region code protection
Speaker 1: is used by the movie studios to thwart an authorized
Speaker 1: duplication of their copyrighted material and to control the worldwide
Speaker 1: release dates. Movie studios agreed to the DVD format when
Speaker 1: DVD manufacturers agreed to put a region code on every disc.
Speaker 1: DVD region locking is used to control which DVD movies
Speaker 1: play in which regions or groups of countries. Movies are
Speaker 1: often released on different dates around the world, Region one
Speaker 1: has its own player that will only play Region one discs. Likewise,
Speaker 1: Region two players only play Region two discs, and so on.
Speaker 1: The six region codes are number one United States and Canada,
Speaker 1: number two, Europe and Japan, number three, Southeast Asia, number four,
Speaker 1: Latin American Australia, number five Russia and the rest of
Speaker 1: Asian Africa, and number six China. Be sure to check
