I've been using DVD X Copy Plat. to backup DVDs. When I needed to make a copy of one of these backups using Nero, I wasn't able to - some sort of data corruption? I know that you can't copy a backup using dvd x copy. So I found this site and saw how it recommends dvd decrypter and shrink. I've been using both - rip it with dvd decrypter then make the DVD with shrink (with some amount of compression). 1) Shrink rips on it's own also?! Why bother with Decrypter? 2) Why make the distinction of dvd5 and dvd9? I've just thrown disks into the drive, let decrypter rip it and then shrink compresses if needed.... or sometimes it'll be at 100%. Am I doing something wrong / setting up a problem later? THANKS!
