MovieTrack is a free program to organize and keep track of your entire movie collection regardless of size. It can handle movies stored on any and every medium such as DVD, DivX, VCD, and VHS and is tightly integrated with the IMDb to retrieve and present the best information on your movies and films for creating a database like no other.

Try it. :)
Personally I use dvd profiler but that only supports dvds. Free download here (http://www.dvdprofiler.com/dvdpro/index.html). Seeing as most of my videos have now been replaced with dvds and put into storage. It also allows you to create an online database of your collection.
