Answer 1

The pictures and the little caddy are written in a special code which cannot be decoded unless you have a guide to the code. This guide to the code is unique for every copy of the movie. The guide to the code is either put on a usb stick and sent separately to the caddy or sent electronically via a secure private network to the movie theatre where it is plugged into the movie projector. The movie server can then send the encoded pictures and sounds to the movie projector which decodes them to play back the actual pictures and sounds in the theatre.
