I think you misunderstand:
Items with NO rating data: Are correctly hidden from a user via parental control, you're right.
Items with a specific rating of "Rated NR": Are being considered as like G rated / safest rated media when they shouldnt be, and are slipping through parental control.
I believe that items with a specific rating of "Rated NR" should be treated the same as an item with No rating, or at least classified as restricted.
Do you follow what I mean?
