Check if that gives you any hint:

Also, some encrypted DVD prevent copying the files in the standard 
manner. IIRC, for dealing with such media I had to first make an 
ISO image with the DVD files and then mount the ISO image to access its 
content... but that was long time ago (1/2 years), not sure if this will 
work nowadays.
