First of all, forgive and forget my english, it's terrible.

I live in Brazil, South America. I bought in U.S. a DVD Samsung model DVD M101, and it is area 1, and a need change the region code to area 4. I didn't find in this site the same model of mine. Can I use the codes related in Samsung DVD M103 or some other code?

If anyone have the correct code to my DVD I will be thankfull!!
