Regional Management Information Code

Most DVD's will have a globe with one or more number(s) in it clearly visible on the cover. If the number of the region where you bought your (unmodified) player is not shown then the DVD don't work with your player. In addition to this you should be aware that in some of the regions there are both PAL and NTSC releases. Most U.S. players only supports NTSC video while most European players supports both NTSC and PAL. In order to play a disc the player need to support both the region and the video format. This means that most players in the USA can't play play an European release even if the player has been modified to become a multiregional player.

There are 3 types of multiregional or "code free" modification for the players:

1. Region 0. This was the first kind of modification. Many DVDs are encoded so that they will not be read by thise player.
2. Autmatic change of region. The discs can be encoded to "fool" the player to change to the wrong region so they become unplayable, but there are no such discs yet.
3. Manual change of region. This is the only type that assures full compatibility.

A disc can also be coded for region 0 or all which means that it can be played on all DVD players(that supports the same video format).

Remark that all the country borders within the DVD regions are not correctly marked and that I have not had time to draw all the borders in region 5.
