VOB + Custom

[Luci]

i was wondering how can you buckup this protection.
for ex sacred (uk) has Vob + Custom.it's not detected unless you look at the cd a file caled Vob.reg(something like that).first disc copied ok.second disk (no protection) copied ok.install the game and 2nd cd sais sectors, textures(i think) and some other cannot be installed.made the image 3-4 times but the same problem.

i want to know if this protection needs hardware requirements.it's not possible my pc not to create a god image.same happens with safedisk v2(just 2 not 2.9etc)
