backup problems

[WeWe]

Hello!!!

I have a V 4 with a Neo 2.2.
Now some of my backups do not work anymore. Like 007 freezes after entering the car on the second mission or Headhunter when getting on the bike.
The copies that use more than 1 CD cause difficulties too.

Originals and copies on just 1 CD as well as PSX copies and originals work fine.
Do you have any suggestions what to do?
I am now thinking to get a Messiah into my PS2


Thanks for your help!!
