For anyone looking for cheap (free) software for tracking your movies/music, check out this site. Its an online inventory system. You can search by names to add titles to your inventory with data pulled from Amazon. You can "check out" dvds/books/cds/games to friends. It also has tagging, so you can make your own lists.
Oh...my favorite feature...you have your own site. (
http://yourname.listal.com) You can send this site to your significant other/parents/etc and they can see what you own and your wishlist in case they want to send you random gifts.
(No, I don't work for them...just found it and thought it was pretty cool.)
