DvD Copy protection?? Please Help!! Important!

[punkrockfan]

Hello y'all,

i have a ps 2 v 7 with a working magic 3 chip.
I use a dvd +burner to backup my games, and i succesfully created around 6 backups with nero.
Then it happened. I tried to backup time splitters 2 and after i succesfully burnt the image, IT DIDNT WORK!!
How can that be? I mean is there any copy protection for exact dvd copies? after some other fine working backups, i have the same problem with Freek style too. Please help, i was in 3 forums now and nobody had an idea ... I heard that primo dvd burning is a good program, maybe that'll do it? i dont want to do further experiments, because 4 not working dvd medias are enough.
(i lost around 10 € with that)
Any of you with a dvd burner, please tell me if you experienced such problems too, or if you succesfully burnt these games and then how.
Another problem that i have is with a cd backup of half-life. Does anyone now if this game is "fade-protected" ? Because after around 5 minutes of playing, the game stops and there are some strange "picture-freezing" errors.

Are there patches in the net wich can repair wrong or protected dvd images?And if yes where can i get these? All that i found was for ripped image files.

If you have any questions about dvd burners or the big "+ or - question", i would be pleased to help you, because after 3 months of searching the net and asking people i am well informed now

Please answer me, even if you just have a guess what could be the problem. And sorry for my english, its a long time ago since i had to write in english at school (i am german).
