+r disks

[fratres]

The advice given here is for ps2 games ( and any dvd movie backup you intend to play on yr ps2) should be burned onto a ritek dye based dvd-r and nothing else....if you want your ps2 laser to work for more than a few months. doesn't matter whos ps2 will run what media. stick to dvd-r and ritek.

Well, at least that is what everybody says. But does -r media really have better reflectivity than +r media of the same brand? I doubt it. Or does the technical difference in the burning process of the two DVD-types make any difference to laser life? Any specialists around?
