I have a whole bunch of Verbatim DVD+R DL dvds, I have successfully burnt COD: World at War with Project X 2.0 on to it, but when I burn GTA IV EFLC with MDv11, nothing comes up when I start the game. the game starts up and functions as a retail copy, no mods. I think it is because I don't have access to the 2.4x write speed, ImgBurn says I can only burn at minimum 4x. Is there any way to force a lower write speed? Please help!
