00:00:00,520 --> 00:00:03,600
Speaker 1: Welcome to brain Stuff from house stuff works dot com

2
00:00:03,600 --> 00:00:14,120
Speaker 1: where smart happens. I am Marshall Brain with today's question

3
00:00:14,400 --> 00:00:17,960
Speaker 1: why can I play some DVD movies but not others

4
00:00:18,079 --> 00:00:23,960
Speaker 1: on my computers? DVD ROM player DVD movies have region codes,

5
00:00:24,040 --> 00:00:27,280
Speaker 1: and they typically only play on a player or DVD

6
00:00:27,400 --> 00:00:30,640
Speaker 1: ROM drives sold in the country where the DVD movie

7
00:00:30,760 --> 00:00:34,920
Speaker 1: was sold. The actual region code is in one byte

8
00:00:35,120 --> 00:00:38,960
Speaker 1: on the DVD. The DVD player or drive has a

9
00:00:39,000 --> 00:00:43,639
Speaker 1: region code and its firmware. Personal computer DVD ROM players

10
00:00:43,800 --> 00:00:47,000
Speaker 1: often have the code either in their software or the

11
00:00:47,159 --> 00:00:51,159
Speaker 1: MPEG two dcoder. The two codes must match for the

12
00:00:51,200 --> 00:00:54,480
Speaker 1: player or drive to play the movie. The code is

13
00:00:54,520 --> 00:00:58,440
Speaker 1: also printed on the back of the DVD package, superimposed

14
00:00:58,480 --> 00:01:02,560
Speaker 1: on a small image of the lobe. Region code protection

15
00:01:02,720 --> 00:01:06,160
Speaker 1: is used by the movie studios to thwart an authorized

16
00:01:06,240 --> 00:01:10,520
Speaker 1: duplication of their copyrighted material and to control the worldwide

17
00:01:10,600 --> 00:01:15,360
Speaker 1: release dates. Movie studios agreed to the DVD format when

18
00:01:15,440 --> 00:01:19,880
Speaker 1: DVD manufacturers agreed to put a region code on every disc.

19
00:01:20,440 --> 00:01:24,720
Speaker 1: DVD region locking is used to control which DVD movies

20
00:01:24,880 --> 00:01:29,240
Speaker 1: play in which regions or groups of countries. Movies are

21
00:01:29,280 --> 00:01:33,000
Speaker 1: often released on different dates around the world, Region one

22
00:01:33,120 --> 00:01:37,479
Speaker 1: has its own player that will only play Region one discs. Likewise,

23
00:01:37,600 --> 00:01:41,240
Speaker 1: Region two players only play Region two discs, and so on.

24
00:01:41,560 --> 00:01:45,679
Speaker 1: The six region codes are number one United States and Canada,

25
00:01:46,040 --> 00:01:50,760
Speaker 1: number two, Europe and Japan, number three, Southeast Asia, number four,
