Filter items without parental ratings

[Pieter]

Hi, how can I filter media to select items that do not have a parental rating set?
I want to make sure all media has ratings, such that I can fix the ratings if not set, so that my kids can watch shows they are supposed to be able to see.
In the filter dropdown I only see ratings, not an items of no rating or unrated?

You can't filter in the UI. But you can install the Reports plugin to filter null ratings.
