I'm new to the 360. I tried to copy game from ISO file. However game just shows xbox 360 log when I tried to play game. Also it show play DVD on home screen. I am following below site. http://www.wikihow.com/Burn-Xbox-360-Games-onto-DVD-Discs Only difference which I found, my dvd writer does not support 2.5x speed. It is only support 4x 8x 16x. Is it causing the issue? Anyone can help to find out what is wrong?
