Both your own explanation and my own experience contradict this. It's the manufacturing quality that is the culprit. If it was the dye, all G05 would degrade, and at about the same rate. They don't, and some even don't degrade at all... I've had G05 dying in three weeks, while other discs, sometimes [i]from the very same batch[/I], are still pristine a year later. The Traxdata I burned are all fine.
Also, don't forget that the issue started with G04, before G05 was even released. Early G04 didn't degrade, while G04 produced since mid-2004 is often afflicted with fast degradation. Same dye... so it's not the dye.
No, I'm pretty sure that the sloppy/rushed manufacturing to meet market demand, ending in discs more or less sealed (heavy bonding, typical of Ritek discs, is no guarantee of proper sealing), allows more or less air contaminants to make contact with the inner materials (the reflective layer is actually more sensitive to oxydation than the dye is, AFAIK - I can be mistaken). Which is close to your own theory.
As the plastifiers used in some DVD/CD cases can generate air contaminants able to degrade the dye if the disc is not properly sealed, we have another possible explanation why some people experience no such degradation, depending on the cases they use. Or if they smoke or not.. etc.. etc..
As for the variation in burning quality (some G05 give outstanding burns while some other burn like crap), I'd blame it on the dye spreading, but this is is conjecture. Like the rest, actually :bigsmile:
