This happens to me also running cinema mode. It takes 10-20 seconds to get the large 'busy' symbol up, then a brief access to the blu-ray drive and the menu appears. When I close the application, it takes another 10-20 seconds to get control back, during which time I can move the mouse but the computer is otherwise unresponsive.
I'm looking into it, but it sounds to me like it's looking for something and timing out.
Performance is otherwise very good.
