DVD player won't play

[RAB302]

I dont see any thing showing thunar on the left panel when inserting in cd in the player. Then went to settings manager, desktop, and icons and dont see anything there resembling to thunar, but everything else there is checked off. I also went to the VLC and change video output to opengl glx video ouput (xcb) and rebooted, still nothing happens.


Also tried from a previous suggestion went to the terminal window and input selected codes and got this:


raymond@RAB-P-6860FX:~$ vlc dvd:///dev/dvd
