DVD hacks allow users to play movies that were produced in other countries on their DVD players. Changing the allowable region code will not change the type of video however. Videos encoded with NTSC will still need to be played on NTSC (North American market) enabled players, and PAL (European market) with PAL players.

DVD regional codes came about as a result of the push for Digital Rights Management (DRM). With the concept of regional codes, movie production and distribution companies could now control when and where a movie would be released, rather than having a DVD hit the entire world market all at once. In addition, differing versions of DVDs could be produced for each region, with the features reflecting the value of pricing for each specific region. Opponents of DRM claim that regional codes area violation of international trade laws, but no legal case has been presented to challenge the idea.DVD Explorer: Can I make my DVD player a multi-region?
