Okay, I've tried to burn GT4 and Rogue galaxy onto dvd+r dl discs, I've burnt them in nero, decrypter, and imgburn. All booktyped, with and without the toxic patch applied. I've also tried two different burners, a samsung and a mastushita. The burns always finish fine and both layers show up through a scan. But, everytime I put them into my MI chipped v7 ps2, the thing won't even try to scan the disc! It will boot like it would without a disc inside. DVD+R backups all worked and have never given me a problem. I know that I can rebuild these, but what I really want is to have working dual layer backups. Since my ps2 doesn't even bother to try to read the discs I'm wondering if something's wrong with my laser. The only other possibility I can think of is that my media is bad, but everyone recommends the verbatims. Any thoughts or confirmation of my ps2 laser being the issue would be helpful.
