Cinematheca

You can use Cinematheca to maintain your own movie collection and also view the list of movies in your friends' collections. It is easy to see if your friend has a new movie and ask him or her to let you see it. You can view your friends' collections even when they are offline.

The software allows you to rate movies and share these ratings with your friends, search your collection and your friends' collections, and group movies into virtual folders.
