I'll.

You are right, the problem has gone after adding -vo x11, now I got a normal picture. But, the video only displays a short picture (1 minute prolog), then it stopped. Confused again...

Let me clarify more, the DVD disk is a DVD-R, my DVD driver is DVD+R, I
suspect that might caused the problem. So, I think if I copy DVD contents to
harddisk in /home/Video then playing from hardisk should fine, but it still did not work. I called following command, please correct me:

mplayer dvd://home/Video/1

Thank you and happy new year.
