This I do not understand either. You gave us that:

So your / is (about) 20 GB (not 50!) of which currently 6.1 GB are 

Having 12GB in use to me seems OK, ex. I am on 32bit Intrepid and my / 
is 9 GB large.

OK then, did you find movies in / ?

I would think this is extremely unlikely.

Nevertheless, you should store your own files, including movies and 
anything else either in /home or /home/backup.

Or is there anything else?

Forget about fdupes. It is a great tool but the command line data flood 
will easily overwhelm you.

My guess is, you issued fdupes without sudo and most of the output was 
permission denied problems, but again, IMHO this is currently not 
important. IMHO you better concentrate on your own data.

Kind regards
