Add to library, even if it`s not in IMDB

Hi

I have some Walt Disney Treasures - something, something movies, that don`t lie in the DB of IMDB.

Is there a way for me to make them show up in the library even if them is not scanned?

I know of the file mode, but this is not the way I want it to work.

I have searched for this problem, tried the wiki. But can`t find anything I understand.

Kindly

Petter
