after checking the sabotuer game with abgx and after burning the dvd file with imgburn i get play dvd on my liteon 1.61
Is ABGX setting the correct layerbreak? Have you played other games on your Xbox before? Sabouter is a Wave 4 game so it should work.
Is this the only game you're having an issue with? Burn at 2.4. Also what media are you using? Verbs? Could also be a bad ISO
