I just recieved a copy of 2001 a space odessy from amazon auctions and it has a dts logo across the top of the disc and it says all ntsc on the back. and it has a circle with dvd 9 dual layer on the upper right side. My reciever recognizes the disc as dts and lets it play. It also has a dd 5.1 track on it. Did I get a bootleg copy, or is this a Euro copy?
