Yeah, I don’t know much about them. I’m sure modern day ones do things like expire and have great encryption and a million ways of watermarking things. 2002 though? Maybe less crazy. But I’ve never heard of someone having such a thing.
Anyway, Padme’s lines were indeed changed. We have the titular Centropy telesync as well as lossless DTS CD rips to confirm that. The “uh huh” change is simply differently dubbed. “To be angry is to be human” is a different cut. Changes the scene length and cuts a few frames from the shot before and the start of the next scene. Not to mention changes the characterization and relationship. Or at least makes her idiocy more obvious.
