DVD Tracker by Winfordtek
There is no flashy and confusing interface .. it just works. When entering DVD information for the first time, simply enter the title and push the "Internet" button. If there is more than one movie by that name you can also enter the year of release. Of course, you can always enter the information by hand. All data is kept on the device so an internet connection is not needed for browsing your collection.
If you loan a DVD to someone, make a quick note in "DVD Tracker" and its title will be highlighted wherever it appears. This acts as a gentle reminder to keep your collection from "walking away".
