Re: assistance

DVD players and DVDs are labeled for operation on within a specific geographical region in the world. For example, the U.S. is in region 1. This means that all DVD players sold in the U.S. are made to region 1 specifications. As a result, region 1 players can only play region 1 discs. That's right, the DVDs themselves are encoded for a specific region. On the back of each DVD package, you will a find a region number (1 thru 6).
The geographical regions are as follows:

REGION 1 -- USA, Canada
REGION 2 -- Japan, Europe, South Africa, Middle East, Greenland
REGION 3 -- S.Korea, Taiwan, Hong Kong, Parts of South East Asia
REGION 4 -- Australia, New Zealand, Latin America (including Mexico)
REGION 5 -- Eastern Europe, Russia, India, Africa
REGION 6 -- China
REGION 7 -- Reserved for Unspecified Special Use
REGION 8 -- Resevered for Cruise Ships, Airlines, etc...
REGION 0 or REGION ALL -- Discs are uncoded and can be played Worldwide, however, PAL discs must be played in a PAL-compatible unit and NTSC discs must be played in an NTSC-compatible unit.

The end result is that DVDs encoded for regions other than Region 1 cannot be played on a region 1 DVD player, also, players marketed for other regions cannot play region 1-stamped DVDs.
