Movienizer is a movie collection manager, and as such it should be able to track where you can find your physical media. There is a Loan Manager for that. If your friends borrow your movies from time to time, it’s a feature you’ll find useful. Loaned movies still remain in your collection, but they are marked as loaned. You can provide any comments and also an expected return day for a movie. The Loan Manager keeps the information even after you get your media back, so it can easily remind you if your friend has already seen a particular movie from your collection.
