Well, if it is R1, then I am pretty sure it would be Harry Potter and the Sorceror's Stone, since both the book and the movie were only released under that name in North America. They figured the Americans would be too uneducated to know what a Philosopher's stone was. As far as I know the only existing NTSC copies of HP and the Philosopher's Stone are DVD-rips of the PAL version with the video converted to NTSC, right?

Must be something deeper to this question than meets the eye, the ADM I know is far more competent in video knowledge than I am and therefore could not be asking such a simple question. ADM, you live in NTSC land, right?
