Help - which DVD is it?

In anticipation of the next Reel Issues film, Minority Report, the owner of our local cinema asked to borrow my DVD copy in case the 35mm version that he has booked isn't up to scratch - or, more to the point, is very scratched.  So I popped it round and left it with the helpful person on the desk. 

About an hour later, I got a phone call from the cinema owner - who does all the projection, has a laptop and DVD projectors in the room that he is calling from, and is clearly reasonably technical - asking for help.  You see my copy of Minority Report has a bonus disc with it and he was ringing to ask which disc had the film on it. 

Tough one, how are we going to figure this one out?
