I'm using a DVD Profiler (from Invelos) complete with names, cover photos, etc. You can also upload your database to the web as backup. In case anything happen to your computer, you can easily retrieve the database from the web. You can use this to keep track both DVD & Blu-ray

Using DVD profiler is convenient & it's great to keep track on your DVD library esp when you want to search for a particular movie or simply to browse tru with your family & friends to look for a nice movie to watch in a cozy evening.
