I think DVD class should not contain start and end date. That needs to be maintained separately by your controller (DVD Library).

How would you find who has taken a particular DVD? This also needs to be maintained by DVD Library

This is the design for library where books are rented. Replace books with dvds and the design should work. thought-works.blogspot.in/2012/11/object-oriented-design-for-library-to.html
