What i did wrong ?

Hello all, i`m from Romania, so sorry for my incorrect english. I have some issues with making "back-up games" for my phat xbox 360 flashed with lt 3.0.. Until some time ago, my cousin was taking care of my xbox problems, but he moved to Germany, so now i have to do it myself. I surfed the internet, and now i know how i should burn the dvds, but i keep failing.. where am i wrong ?

First of all i use maxell dvd+r dl like this one.. where i live, is not easy to obtain verbatins..

From what i understood, beacuse of the xdg3 security, now games have a bigger size than the blank dvds, so i bought a new dvd-writer wich is compatible BurnerMax. (DVD-Writer LiteOn IHAS124-14 bulk black - PC Garage). Did i picked a good one ?



I watched a lot of youtube videos, and i tried 3 different imgburn settings.. for example i used this game "2014 FIFA World Cup Brazil.." i dont play on xbox live, and i dont connect my console to the internet, so i`m not preoccupied with baning..
Could the fact that i burn the dvds at 4x speed be the problem ? when is 50% approximative, the buring process stops. It`s the dvd writer the problem ? could you please give me a correct way, or a tutorial to burn games on this kind of blank dvds?

Thanks!!
