You can change the region code for your DVD player but not more than 4 times.
There are firnware updates to change DVDs to region free, if you are not carefull you can screw up your DVD drive.
Suggest you install a program to allow you to play any DVDs regardless of which region the DVDs were created for.
Go to www.dvdidle.com for their Region-Free program

You can only change the region code up to 4 times then it locks on the last change.
There are some firmware upgrades that can change the drive to region free, if you can screw it up or put in the wrong frmware upgrade then the DVD drive will be a piece on junk.
I suggest you install a region free software that will allow you to play any region DVDs.
Go to www.dvdidle.com to get their Region-Free software, it is not very expensive.

The region code can only be changed 4 times and it locks on the 4th change.
There may be a firmware upgrade that make your DVD region free, but if you make a mistake or install the wrong firmware upgrade then the DVD will be a piece of junk. You will need to Google search for DVD firmware upgrades for your model DVD.
The best way to view DVDs from other regions is to install a piece of software that defeats the region code. I use a program called DVD-RegionFree from
www.dvdidle.com
There are possibly other programs available, again Google search for them.
