There are a couple ways to go about changing your region on your DVD player. First is this program:
DVD Region+CSS Free - Watch & Copy Any DVD!
Region+CSS Free enables you to watch and copy any
region-coded/CSS-encrypted DVD movies on any DVD drive! It fully
supports region-protected (RPC2) DVD drives, and does not require any
firmware modifications. It will even work if you have used up your
region counter and can no longer change the DVD drive's region.
DVD Region+CSS Free works automatically in the background to make a DVD
appear region code free and unprotected to any DVD player and DVD copy
software. With the help of DVD Region+CSS Free, you can watch any
region coded DVD movies with a software DVD player like PowerDVD or
WinDVD! With DVD Region+CSS Free's help, DVD copy software (such as
DVDFab, DVD X Copy, InterVideo DVD Copy, etc.) is able to copy DVD's
which are CSS protected!
New Feature: DVD Region+CSS Free decrypts not just DVD's, it now allows you also to play, copy and rip protected Audio CD's!
