unusual dvd problem
 

I've been trying to get my computer to play dvds using totem movie player but i get an error message that says "could not read from resource". This happens sometimes !

A newspaper dvd with morse on it fine! A commercial dvd carry on something , no joy.

I have installed the xtras, and this an unusual problem.
any ideas?
