PS2 v9/10 laser (reading disc) issue

[MystD]

I use Verbatim CD-Rs and Yakumo DVD-Rs, but if I use the verbatim CD-Rs its the same like using cheap media, it's still "squeaking". Should I still use em? Also my copy of Way of the Samurai dosn't work normally, the original works fine, but if I use the backup (its on a Yakumo 4x, burnd in 1x) the viedo sequences are "lagging" like using dvix in high res with an old cpu.
