This may be of help to anyone who has access to a Linux system. I thought I had posted this but I cannot find it, if I'm being redundant please accept my apologies.
Insert the DVD in drive and unmount it !
#dd if=/dev/hda of=/tfs/xxxxxxxxxxx.iso
Do this for all 3 discs, backup the iso files with your regular backups and create a copied set. These will only work for YOUR laptop, but it's nice to know that if something happens to your original set, you can crete a new one.
I have used my copies on 2 occasions and they work fine.
