DVD-Dycrypter, DVD2AVI, TMPEG, IFO edit. These 4 softwares is the best for a dvd backup on a DVD-R. Follow the guids in the WWW.Doom9.org website. I think anyone can back up a dvd without having problems with those 4 softwares. Those are shareware programs and best as far I know. Enjoy your Backup copies and enjoy burnig.
I'm in no position to disagree with you mate but a simple comment - why do you have to have 4 different programs when one will do the job just as well? I'm talking about DVD Shrink of course. Not only that but it's freeware too.
