I have not had the good luck that sanford42 had with DVDs because I'm having trouble getting my DVD movies to play. Totem will play them, but the upper half of the screen is scrambled. MPlayer's splash screen is all womper-jawed (sorry for those who may try a translator the that one) gives me a fatal error saying "Error opening/initializing the selected video_out (-vo) device. Do I need to reconfig something?
Try to change the video output for mplayer to see if one works better than the others.
Well, that did it. The splash screen is still slaunch-wise, but x11 is the only one that doesn't give an error, complain about packet overload, or has the sound out of sync. However, even it pauses the playback occasionally.
