if only things were that simple jack, (heres a copy of what wiki has to say about it:-
DVD region codes are a
digital-rights management technique designed to allow
film distributors to control aspects of a release, including content, release date, and price, according to the region.
DVD video discs may be encoded with a region code restricting the area of the world in which they can be played.
The American DVD Copy Control Association in California requires that
DVD-player manufacturers incorporate the regional-playback control (RPC) system – according to the
Australian Competition and Consumer Commission, an Australian government agency.
There are six different official regions and two informal variations DVDs may use one code, a combination of codes (Multi-Region), most codes (Region 0) or every code/no codes (Region All). The commercial DVD player specification requires that a player to be sold in a given place not play discs encoded for a different region; however,
region-free DVD players are also commercially available. In addition, many DVD players can be modified to be
region-free, allowing playback of all discs.
