DVD_RW drive not reading some DVDs



I know whats going on (Silvervision Region 2 DVDs), and I know how to fix it (D, but there is one problem that has to be addressed before I can fix it. How would I get by drive to even read the DVD so I can actually go in and delete the ‘cells’ that has the copy protection on it?

I will be using AnyDVD or CloneDVD to make a backup, if that will help.
