I bought two boxes of 200 of those during the boxing day sale. They are fantastic discs for the price, but since I upgraded the firmware and started a new spindle of 100, I've been getting quality score anywhere from a horrid 40-something to low-90s. I used to consistently get mid-to-high 90s for my first spindle of 100 I burned.
I'm guessing that either this is a spindle of lower quality discs, or the firmware screwed up my drive (which is unlikely). I've tried older firmwares and close to the end of the disc I get a lot of PI errors -- I think I got a bad spindle. Anyway, how do you disable WOPC in decrypter?
