Burning with Nero

Hey, I am trying to write make copies of DVDs with Nero Express, but I am getting an error that says,
“This DVD is copy protected and cannot be read”
Is there any way that I can get around that? Like is there a file I can delete in the program directory so that it won’t read that message or something?

Thanks for your help

If you want to use Nero for backup a dvd you need Any DVD or DVD Idle Pro install.Some softwares can pass the protection and here you have a list : http://dvd-copy-software-review.toptenreviews.com/?ttreng=1&ttrkey=dvd+squeeze
