PS2 v9/10 laser (reading disc) issue

[MystD]

Well, I finaly got my PS2 with Ripper 2 gold. But since I've read that the new PS2 consoles have probelms with no-name CD-R/DVD-R, like the laser get's f*****. I got pretty cautious. I've got some old PSX games on 4x Verbatim CD-R. (they work fine, no sounds, reads fast, etc., my PS2 Originals too) But if I insert 48x CD-R media (Verbatim/Sony) the drive makes a lot of noise, but the data ist burned in 4x. I would like to know if it's bad for the PS2, cause it has problems reading the CD-R media or if its normal. If u know some better CD-R media plz tell me.
