Dezone a dvd player

Can somebody tell me how I can de zone my smsung tsh552.
I got the dvd writer yesterday and when I put a zone one disk in I got a message saying I only have 4 more times at playing region 1 disks
It is cheaper for me to import zone 1 movies with shipping costs then it is to buy zone 2 movies locally.

you can check to see if your dvd writer has a region-free firmware available at www.rpc1.org
