Ant Movie Catalog is a free (really free, i.e. the source code is available) program made to manage your collection of movies DVD, CD (VideoCD, DivX, …) and tapes.
If you use GNU/Linux rather than Windows, you can try to use WinE to get this program running. You can also check Moviefly, which is a complete rewrite of Ant Movie Catalog made with Python.
