I used xbcopy to copy the espn nba tonight 2002 to my xbox hd. I found out the game on hd will work only if the dvd-rom of xbox is playing some original. When I ftp the files to my pc and make a dvd-r backup. It won't work. Since this is a japanese release, I wonder if this is a copy protection implemented by them.

Can anyone figure out how I can play backup dvd-r of this title?
