Basically all commercial dvds with the exception of stuff like some independent releases and essentially all blurays have copy protection (CSS for dvd and AACS for bluray, for bluray it’s built into the spec)

They’re both fairly trivially defeated (for dvd extremely so because CSS is completely broken, whereas br has key revocation so it’s technically a bit more complex though practically this doesn’t mean much)

I don’t know much about Germanys laws but iirc they are one of the places that takes piracy and torrenting more seriously, no?
