I have to admit that I am a complete kinda newbie in DVD-copy field, though had a chance to watch the progress.
Relying on my poor personal experience and on the rich experience of my friends, I would suggest: forget any software, just try to use AnyDVD and CloneDVD. Why? Answer is simple:
AnyDVD works calmly and effectively in the background. You just put the DVD in the driver. In 2 seconds it is "free". And now you make the first click, CloneDVD. It makes everything for you, no voodoo, no adventures in Chapters, subtitle and other sections. It keeps everything in one firm hand. You just click, usually on OK without any changes. The movie is "done" in less than 40 mins. There exists no easier, time-saving method. And finally. The quality of the copy is perfect. I was sceptical, but have to admit that it is simply a genuine work.
So, that is the advice. No ripper-here-and-there-click-here-or-there software. Just use two simple progs and you have your perfect copie.
