Fussy Laser will adjusting it help?

[elkayps2]

O.k I have had a couple of ps2's my first was a version 1 Pal with neo 2.2 , that one seems to like Apple and Verbatim Dvd-rs as well as the cheaper brands, my new one a V7 Pal with magic 2, hates verything except apple or verbatim dvd-r's is it possible to adjust/calibrate the laser to like the less reflective dvd-rs?

I have a heap of titles backed up on the cheaper dvd-r as they use to work fine, now I'm looking at investing in a stack of expensive ones just to get my old games to work on the new machine.

any suggestions???
