My best guess is that one or more of my orders for discs(T-Y 8X -r) contained a whole buncha flakey discs that fail over time(8mos.-2yrs.)and they've only recently begun to show themselves.Either that or disc manufacture quality has taken a hit.So far as i can recall,none of my Verbatim DLP discs has failed,only the T-Y's.My question about magnets affecting discs is a reaction to an unfortunate co-incidence that has clouded the waters and caused unnecessary confusion
It is quite possible that you have stumbled on a bad batch of disks. I had a number of JVC T-Y disks fail, and oddly enough, every on the the cake box that failed, did so at exactly the same point on the disk (as measured by the EHxx in terms f how much has been written to the disk in a percentage). All six of the ones that failed, did so at the same percentage. I changed from maximum speed dub, to what the Panasonics call Silent Mode, which I think is 4x rather than 8x, and the problems went away. I now use silent mode on all my recorders. The time savings is not significant enough to make it worth the gamble of a bad burn.

I sure wouldn't risk that kind of exposure to my archives on optical discs. Some here may argue that there is no evidence of discs going bad if exposed to direct sunlight - that's fine, my only argument back is my archives on optical disc playback just fine
with my storage and handling methods.
The Navy did a study, and I can assure you that they found direct sunlight will cause otherwise good disks, that have been properly written to, to fail in a very short time, regardless of the brand (they used a half a dozen disk brands labeled "archive quality").
If I were to make an off-the-wall guess as to the issues you are having, it COULD be, and I don't know if what I am suggesting is even possible, so I will be corrected if I'm totally off base here, that the laser in your mahine is getting old and losing intensity, or at the very least, the power supply board is going out of spec, and the laser is losing intensity. Again, just a wild guess.
