Navigationpack Error



Hey…i’m trying to copy a protected dvd on cloneDVD and about 2 minutes after i begin copying, using the “DVD files” feature, it says Creation of DVD files was not successful: NavigationPack 6 615 7 5 VOBU 4 615 7 TCE

I do also have AnyDVD

So if anyone can help me i would greatly appreciate it…and please also explain it in simplier terms cuz i don’t understand certain terms. I was also reading another post similar to mine with someone giving advice about creating an .ISO file and then mounitng it and pointing it to CloneDVD?? can anyone explain that to me
