Thread: Backing up games

Hi guys,
I wanted to back up a few games that i've got because i've got two computers in different places so rather than lug all the disks around I wanted to have a set for one of my computer and a set for the other.
It works fine for some older games that are on CDs but the more recent games like battle for middle earth and settlers heritage of kings are on DVD-roms rather than just DVDs, this means that they copy fine but for some reason when i go to play the game after installing it, i get a message saying that the disk isnt in the drive.

Is there a way of copying the disks so that they are in DVD-Rom format?

Thanks to all those who reply.
