I have two DVDs with problems, but have not tried to find out what actually goes wrong... 1) The German DVD of Disney's Alice in Wonderland (movie is from 2010) [see http://en.wikipedia.org/wiki/Alice_in_Wonderland_(2010_film) ] -> Can be played on GNU/Linux using dvdnav via VLC or MPlayer, but does not work with dvdread using MPlayer (mplayer dvd://). 2) The German DVD of The Dark Knight (movie is from 2008) [see http://en.wikipedia.org/wiki/The_Dark_Knight_(film) ] -> Does not work at all with VLC or MPlayer on GNU/Linux.
