I've tried several collection management applications, and DVD Profiler is the only one with an adequate database. I want to catalog the EXACT version of the DVD/Blu-rays that I own, and DVD Profiler's database is the only one that comes close. Especially with the 600+ OOP and rare imports that I have and love. When you start collecting imports, you quickly realize there can be an astounding number of releases all with wildly varying degrees of quality (audio, video, subtitles, cut/uncut, packaging, special features, etc), and certain versions become highly sought-after or rare. As a collector, this is very important to me.
