Cause: The movie is region locked, and will only play on a DVD drive that has the same region code. To control the release of their movies, the motion picture group divided the world into seven regions or zones. Each zone has its own region or zone number. When a specific movie is released in a particular zone, it is encod ed with the zone number. DVD players, too, have a zone number. Hence, a movie released in America plays on all DVD players man ufactured in the US, but not on DVD players manufactured in India such as those from Onida, Mitashi, Sony, etc.
Solution: Many DVD players can be hacked using software to do away with the region locking encryption. This voids the warranty, but it isn’t illegal to do so. On some drives, however, you need to modify the chip to make it all-region playable.
