LTD163D RPC-1 Utility

Is this safe to do?
I just bought a Liteon LTD163D and was disappointed to know LTD163D and most DVD-ROM drives have this region checking feature.

I saw that for LTD163D there is a utility that I can use to disable region checking. But is this safe?

Where can I get the latest version for this utility?
