I was having the exact same problem. I spent hours fixing things, double checking to have libdvdcss2, libdvdread3, ubuntu-restricted-extras, and whatever else installed. I tried playing several of the .VOB files, and some of them worked, so I think it was a menu issue. In any case, this last step worked for me.

Thanks Kilinski.
