Where did the Catholic Church condemn naming guardian angels?

I was listening to episode 24 of the Catholic Man Show and they said (without citation) that the Catholic Church has condemned naming guardian angels. The reason they gave was because God gave man the authority over created things on Earth (Through Adam in Genesis). So what basis and where did the Catholic Church make this pronouncement. And should we burn our children's videos with a contrary teaching? (i.e. CCC Video - My Secret Friend, A Guardian Angel)
