Could someone please explain me how this is possible. I have backupped a game to dvd+r (and also to dvd-r). My Xbox recognizes discs as game discs, and starts to load game, but sooner or later I get bluescreen with error message "disk problem bla bla bla". So, I cannot play the game directly from dvd+-r. However, I can copy the game (by using tools provided with slayers evox installer) from the same dvd and after that play the game from HDD. So the dvd drive can copy the game to hdd. How is this possible, why it does not allow to play directly from the dvd? Is there anything I could do to solve the problem? DVD drive is manufactured by Philips.
