I have a few questions about the burning process 1# Do I need to have iextreme firmware, and if I dont what will or will i not need to do when I burn games 2# How do I tell if I have iextreme firmware in the first place. 3# my two earlier burned memorex dvd+r dl gave me a message when I put it in my xbox 360 it said something along the line of "you need to put it in an xbox 360" in several different languages what does this mean? and how do I get them to work? 4# I have one memorex dvd+r dl left, what are the chances of it working even in I burn it correctly. 5# what exactly is stealth patching, xdvdmulleter, and Iextreme firmware 6# How do I tell if my xbox 360 has a hitachi drive.
