I recently purchased a Recovery DVD for a computer that had a hard drive to meet it's maker and didn't have a restore disk. Well anyway, my first instinct was to back it up. I used Unlead Movie Factory to begin with and it went through the motions of copying a DVD then when the burn process was to begin, it came back not enough space on disk. Ok, I wasn't even thinking that was actually the case, so I tried Nero with the same result. Ok, now I'm looking closer at the size of the DVD and it is 5.13 GB and a DVD will only hold 4.7 GB. So how did they get that much more data on a DVD? I'd like to back up this disk but I don't know how. Can somebody please help me?
