How to watch DVD with xine?

Hello SuSE folkz, I've finaly managed to install xine (libraries and interface). Now my question is about how to actually play DVD with this darn thing? I insert DVD disk in my DVD ROM and start xine interface. Xine comes up but nothing happening. It just plainly doesn't see DVD in the drive. Should I mount DVD somehow in order for xine to see it? Could somebody please help me with this issue or point to the source of information. Thanks in advance. Alex
