On the back on the bottom. And I just read all the reviews of it on amazon USA (some of which obviously came from here
), and it seems most people had the same problem as I did. Amazon (I got mine from ebay) says it plays on all dvd players, but reviews stated that informaton is incorrect. Be very careful, sumi1, or you will fall into the same hole. But either way, it will play on a computer dvd drive, guaranteed!
