Some research brought up a program called
GCstar. It can used to keep track of your DVDs, CDs, books, music and even video games. Just enter the name of a movie and GCstar will try to fetch the movie information for you on the internet. It'll allow you to store information such as the director, the cast, the genre, a short description, the DVD cover and a movie clip. It looks pretty good too (

sudo apt-get install gcstar in a terminal to download and install the program.
If that doesn't satisfy your needs, here's another program to manage your DVD collection:
