INFORMATIONSREGIONAL CODES1222554436Map of DVD RegionsWhat are regional codes?Motion picture studios want to control the home release of movies in different countries because theater releases arentsimultaneous (a movie may come out on DVD in the US when its just hitting screens in Europe). Therefore they haverequired that the DVD standard include codes which can be used to lock out the playback of certain discs in certain geo-graphical regions. Players sold in each region will have that regions code built into the player. The player will refuse to playthese region coded discs which are not allowed in the region. However, regional codes are entirely optional. Discs withoutcodes will play on any player in any country. Some studios have already announced that only their new releases will haveregional codes. There are six regions: 1. United States and Canada 2. Europe and Japan 3. Far East (except Japan & China) 4. South America and Oceania 5. Africa and the Middle East 6. China (except Hong Kong)3Playable DiscsDVD video discs(8 cm / 12 cm disc)DVD audio discs(8 cm / 12 cm disc)Video CD (VCD) (8 cm / 12 cm disc)Audio CD (8 cm / 12 cm disc)In addition, this unit can play a HDCD, DVD-R,DVDRW, Kodak PICTURE CD, SVCD, and CD-R orCD-RW that contains audio titles, MP3, WMA or JPEGfiles.Notes Depending on the conditions of the recording equip-ment or the CD-R/RW (or DVD-R/RW) disc itself,some CD-R/RW (or DVD-R/RW) discs cannot beplayed on the unit.
