backup protected dvds

I want to create backup copies of my favorite DVD collections and I tried Nero but it said that the DVDs are protected. I tried looking for another software and I found this list of DVD copy software that claimed to be the best for copying protected DVDs. I need a feedback from someone who has tried using any of these software before I'll buy one. I just want to make sure so I can burn my DVDs and not my money. If you have any other suggestions or recommendations I would really appreciate it.
