It should, but it doesn't. It only copies the first 9MB which, on 
checking, copied the previews and ads from Disney (which were almost 
more annoying than this problem in the first place).

The way I usually do this is with brasero, just right-clicking and let 
it do the rest.

I'm about to just not buy any more DVDs from Disney and switch to 
rental-only or go all-out pirate (admittedly an easier option). DVDs and 
Bluerays are way too expensive to let decay with no ability to copy them 
for legal use.
