Did you read the API to find out other values for the setDefaultCloseOperation(...) method?

You can use:

DISPOSE_ON_CLOSE - the frame will close. If this is the last open frame for the application then the JVM will terminate as well

HIDE_ON_CLOSE - the frame is just set to invisible.

when user clicks the one that says new a new jframe from another class comes up with fields to enter information about a new dvd.

The real problem with your program is that you are using a frame as the popup window. You should be using a modal JDialog. An application should only ever have a single JFrame with multiple dialogs to gather additional information. A JDialog does not allow you to use EXIT_ON_CLOSE.
