Using only the current dvdcss lib does not solve the problem (afaik, I 
have to verify this), but the usage of DVDnav should. Not DVD menus per 
se, but the correct implementation of the DVD VM, following all Cell 
Commands, which is very loosely implemented in current mplayer and 
therefore falls in the pits the copy protection creates. I'll try the 
patch mentioned before on mplayer to see if it bears any luck later this 
evening!
