So I have a previous thread about making a spare copy of a disk. The disk is a DVD, and my Mac has a super drive. From my understanding, DVDs hold up to 4GB. Problem is the sims 3 is 5.96GB and is a DVD. I didn't know that there ate DVDs later than 4GB. It seems that my blank DVDs hold upto 4. Something GB. Are there DVDs larger than 4GB for retail? Will my mac be able to burn a 5GB image? Also are these larger DVDs called duo layer or something? Can I buy a pack at Staples or the Apple Store? Thanks for clearing the confusion. -ouimetnick.
