(please PM me if the links stop working)

Unfortunately, the video at that link is not "Think of Me First as a Person", the original movie that was inducted into the National Film Registry.

"My Favorite Child", the short documentary at the link, was made 40 years later and is a bonus feature on the "Think of Me First as a Person" DVD, only available through the film's official website:

So "Think of Me First as a Person" should not be checked if you've only watched "My Favorite Child".

Thanks so much! Been looking for this one for years!
