Although I understand this is no consolation to linux users there are 
numerous windows tools for playing DVDs with all kinds of protection. 
The reason this is interesting even if you don't use windows is that it 
indicates that it is at least technically possible.  Maybe if an mplayer

Read the list of features at http://www.dvdidle.com/dvd-region-free.htm  
for example. (Some of the tools are free I believe.)
