PS2 Backups - are some games protected??

[hilly]

Help!!

I am trying to backup my Lord of The Rings (UK PAL), Smackdown Shut Your Mouth and MOH Frontline games but am having no luck. When I backup my other stuff I have no probs. Are some PS2 games protected? If so are there patches available? I am using the brand new NEO Premium Media (generation4.3).

Please help dudes! : (

Thanks
