Need Liteon SOHW-1633SX-03 multi-region

I have just bought a new Liteon SOHW-1633SX-03 (USB2 dual layer DVDR). Does anyone know how I can make it multi region ? Thanks in advance

Please take a look at the LiteOn tools collection sticky.

Thanks a lot. Being new to the site it is taking me time to find my way around. Appreciate the help - Jon

Well, I have tried this and the messages that the forum said it should display were as they say they should be, however, when I fire up PowerDVD (even after re-boot) it still asks me if I want to switch region (4 chances to go). Any suggestions?

Take a look at this:

I used DVD Region Killer and it works fine. I really appreciate your help and guidance on this. Many many thanks
