wrong cd`s?

[Ghetto Pimp]

I had a version 4 with a non-solder chip which after a swap trick would boot 74min toc games but not 80min,
so i got my self a version 5 and had a messiah2 chip installed,
this seemed fine on 80min toc but most of the games which worked fine on the version 4 dont work
i wondering if its the media im using...i use TDK dview.
