First off I'm not sure if your xbox is external or if your computer is. If it is your computer it shouldn't matter just as long as it is a dual layer disk burner. But if your xbox is external (don't know how you did that) then it won't work. But if the xbox is internal then I think I know what the problem is. Well if the DVD drive is not flashed with the latest firmware then you cannot just pop it in and play it. What you need to do is hotswap the game with the original. If you don't know how to do that there are tons of tutorials on here just look around

Hope I helped.

i know how to hotswap ive done it before my friend gave me a ISO but now i want to make my own and update to newer patches

ModdzzFTW wrote ok so this would be my 2nd attempt at ISO Mods.My ISO were made for me by a friend but hes fixing his computer so i cant get one from him.So back to the point.My dvd drive is a External USB DVD Drive.It is a DL Disk burner but when i burn the disk and play the iso to my xbox it doesnt work it says disk is unreadable so i know something is wrong.

Im just wondering if its cause i have a External DVD Drive and not a Internal Please respond back if thats why it doesnt work

Are you hotswapping with an open xbox, or with the glitch ?
