At any rate, I've been using DVD Profiler since 2001. It is both a web site AND a program. The program runs on your PC and has more features than you can shake a stick at. The web site provides you an online listing of all your DVD's.
I urge you to check it out. If nothing else than to understand what the competition has to offer.
