LITEON DVD-ROM LTD163D - multizoning / dezoning

I have recently aquired a LTD163D, however I hate being told I can only change my zone 5 times when I know the Hardware is being unnecesarily limited.

Question One

Where is the zoning implentation, firmware or software?

Question Two

How is this limitation overcome to use DVD from all zones?

I look forward to your replies.



Normally there is a protection in both firmware AND software.

Grab the utility to turn off RPC protection for Lite-On LTD163/LTD-163D here.


Type R1211 “x” OFF

Where “x” is a number from 1 to 4:

Primary Master 1
Primary Slave 2
Secondary Master 3
Secondary Slave 4

Then you also have to bypass the protection in the program. By using programs such as DVD Genie for example. Try a search on google for this program;)

why not use Region Killer??? what about this program?


Rpc2 is hardware based region protection. Besides this you have software based region protection… Region Killer is an example of a software based check.

This forum is great,
I hope that I can contribute to it at some point.:smiley:
