DoubleDips

This is a program that will help you to find out which titles you have duplicates of.

You can select your columns, and the order of columns too. There is also a function to weed out same titles with adjacent production years.

You can fix those titles where one of them has a production year that is off by one year. It happens more often than you think!

Unlike a plugin, this program can run independent of DVD Profiler, so it doesn't lock up Profiler.
