Ok so I got my 360 modded, I'm using xbox back up creator v2.3. I can copy the games then I go to burn them in my LG drive and I select the .iso file. It burns for about an hour, then the box wont read it. What im I doing wrong, im I supposed to put the .dvd file on the disk too (if so how do I do this?).

You don't select the iso file for burning you select the .dvd file. Right clikc the .dvd file and select burn using imgburn (if thats what your using) and make sure your only burning @ 2.4x. Verbatim disks work best.

Plse take the time to explorer the pinned section at the top of the forum ( Backup Faq - Everything* You Need To Know PLEASE READ BEFORE ASKING QUESTIONS! ) as many of your questions are covered there.

I will also direct you to the following sections.
You will find a very good overview document here

Imgburn tutorial for burning games here

Also look at the newbie section for most of the questions we all have when we begin .
