DVD Profiler can manage any size DVD collection. It is Internet connected for sharing profiles. DVD Profiler connects to the online DVD database at Invelos. Invelos maintains a constantly growing database of DVDs. Each DVD is entered by one user and shared with all users. If you find an error, you can correct it and automatically share your correction with everyone. Since the database is user-built, it will keep growing. Entry into the collection is one step. Enter the UPC from the DVD Case, and DVD Profiler will retrieve the DVD profile from the online database. If you have a DVD-ROM drive, it's even easier: put the DVD in the drive and DVD Profiler asks if you would like to add it.
