The DVD region coding has absolutely nothing to do with encryption. It's just a random bit field that decoders happen to pay attention to.
What you're referring to is the Content Scrambling System, which is a protocol that negotiates a session key between the reader and the decoder, via the host CPU, using a proprietary hash algorithm. If CSS is enabled on a title (a subset of a disc), the reader will refuse to read that title until the CSS negotiation has been successfully completed.
Officially, you have to pay 5 kilobucks to Matsushita and sign a bunch of NDAs to get the CSS spec. It's almost certainly possible to reverse-engineer it from a software decoder implementation (such as the one that ships with some Compaq desktops), but I have yet to see anyone publish the results of such an effort.
