SPRM 20: Player Region Code
In order to have some control over which parts of the world can play a disc, a regional
coding system was developed. With this system, all standalone DVD players are
manufactured to support a single region, and DVD players used by computers have a
setting that configures the player’s region (with a limited number of changes allowed).
This SPRM returns the value of the DVD player’s region code.
