"It isn't illegal to have a copy if you have the original. It is however illegal if you don't have the original."
Wrong. A lot of armchair lawyers here. Go to law school, take a copyright class, then come back here and post. It is not legal to copy DVDs and Games, even for backup purposes. You probably will not get in trouble for it, but the DMCA does NOT allow for this. Ask any copyright expert, and they will tell you the same.
