I just had a question from Cerpts over at The Land Of Cerpts And Honey about movie-collection databases, so I thought I'd share the software that we use for our DB. It's Movie Organizer and it works fairly simply. Type in a movie name, hit F7 and it searches both Movie Organizer's own database as well as The Internet Movie Data Base for the film. Printing out a listing is fairly simple, too. It's freeware and has been around for over 10 years.
Of course, not every bit of software suits everyone, and this one is PC only, so give it a go if you like and let me know what you think.
