Small suggestion

In large database with many registration, a future like "find duplicate" will be very usefull.

This can be done through script. Even if it is not the best solution, it works more or less well.
Go to Tools -> Scripting, be sure that the "movies to include" option is set to "all", then in the list launch "find duplicate" scripts.
You will find the result of the process in c:\duplicates.txt

Thanks for answer.It's OK, but find duplicates only in titles. I have two version "remake" and new movies with same title.
But with some hand-work it' alright

You can modify the script to add a check on the year too.
