Can someone pls help a newbie?

I have just received a new Sony DVD burner, and want to copy protected movies. I have tried AnyDVD - used it in the background to remove protection. It disrupted my Norton Internet Security 2005 (up to date) and I had trouble even reinstalling Norton from my system as it locked me out.

Can anyone recommend something to go with Nero 6 SE so that I can remove the copy protection without disrupting my anti virus software?

Thanks.
