I've been using mplayer for a while now, so I know this isn't a configuration error. I foudn this error when I was encoding American Beauty. It always "finished" after chapter 18.I opened it to view. When I get to chapter 19, the display becomes a mess. The console scrolls "encrypted stream but authentication was not requested by you" constantly. I've cleaned the DVD and the player. This is the only DVD I have this problem with, and it's always at chapter 19. I'm running Evil Entity Linux 0.2.5. Mplayer 0.90pre5-3.1. Kernel 2.4.20. Enlightenment.
