regional
codes
that help control DVD title exports
and help reduce illegal disc distribution.
To be able to play a DVD, the disc’s
regional code and your DVD drive’s
regional code must match.
The regional code on your DVD drive is
determined by your computer’s delivery
address. The regional code for the United
States and Canada is 1. The regional code
for Mexico is 4. Your DVD drive’s regional
code must match the regional code for
the disc. The regional code for the disc is
on the disc, disc documentation, or disc
packaging.
If the DVD movie does not play, the disc’s
regional code and your DVD drive’s
regional code may not match.
