Microsoft Xbox 360 consoles utilise dual-layered DVD discs that can hold up to 8.5 GB of data each. You can copy and burn your Xbox 360 games to a dual-layered DVD (DVD+DL) using freeware software from the Internet. Copying your 360 game will take about 30 minutes.
Turn on your computer and open an Internet browser. Select a disc-copying program from the list in the References section (below) and download it from the developer's website. Install the program, then reboot the computer.
Run the disc-copying program and eject the burner's disc tray. Insert an Xbox 360 game and close the tray. Click "Copy DVD to .ISO" in the program's main menu and type a title for the .ISO disc image file being created on your computer. A disc image or .ISO file is a backup of the entire DVD that can then be easily burnt to a disc. Wait for the .ISO copy process to complete before continuing.
Eject the disc tray and place a DVD+DL inside. Close the tray and click "Burn .ISO to DVD." Type a title for the DVD being burnt and select the .ISO file you just created. Select a disc burn speed (Pick 1x, 2x or 4x to avoid high-speed hardware errors when burning) then click "OK." The program will create a burnt backup copy of the Xbox 360 game. You can use the disc as soon as the application finishes the recording session.
Do not copy Xbox 360 games you do not own. Doing so violates federal copyright law.
