Xine sound but no picture
I run Mandrake 10 on an emachines M5116 laptop. I have both Xine and MPlayer installed and both were working fine. Now, all of a sudden, I have a problem. When I try to play a DVD with Xine, I get sound but no picture. When I try MPLayer, I get nothing at all. However, I can start MPlayer, try to play DVD then quit MPlayer (but the MPlayer window freezes on screen) and then start Xine and it will play both sound and picture!
Can anyone tell me what is going on and how I can fix it?
