DVD Copy Protection - Backing Up difficult?

[fratres]

Hi,
more and more I find hints on newer DVD-based PAL-PS2-Games saying "this game is protected against copying".
I found this on Ratchet and Clank 2, Dark Alliance 2 and some more I can´t remember right now.
Is that a new copy protection for DVD (haven´t found anything about it in the forum), are they using DVD9, or is it still possible to backup those games 1:1 as simple as it used to be (I used Nero, and even DVD+R works on my V3, using SwapMagic 2.0). Or do I have to use DVDDecryptor or DVD Shrink or something else to backup these games?
Please help!
