Use Anydvd with VobBlanker version 2.2.0.1 which is free software follow link:
http://www.free-codecs.com/VobBlanker_download.htm then run processed files thru Dvd Shrink and burn.
All Sony ARcoSS protected discs which include Layer Cake, Little Black Book,
Resident Evil 2 and The Forgotten have all backed up first time using this method. I use Lite-On 1633s x16 Dual Layer burner with Traxdata 8xDvd-r disks.
