Ah, we confuse some things here.

I was talking about the Region Code, _you_ were talking about the
RPC Phase.

drive), where I am allowd to change the Region-Code-Number in the
firmware for 5 times, before it gets fixed and stays at the last value.

But with libdvdcss, you don't have to change the drives Region Code
Number, because libdvdcss does not authenticate the drive with the DVD,
it just happily cracks along the needed keys and uses them without
asking the DVD-Drive to get them (as far as I understood the mechanism).

So I am able to play DVDs with every Region-Code _without_ having to set
the Region Code of the drive to match the one of the DVD.
