Sony DRU-710A won't read DVD+RW media anymore! Help!



I’ve been using Memorex DVD+RW’s for years, and more recently Verbatim DVD+RW’s, but after upgrading firmware BYX4 to BYX5, suddenly it won’t recognize anymore. It still reads/writes DVD+R’s, though. I also recently uninstalled & re-installed some Nero software that wasn’t working right, so I don’t know if that had anything to with it. This is very frustrating, as I’ve tried several of the standard fixes such as system restore to a couple days ago, installing the drive onto another computer (didn’t work), checking ASPI (was fine), and turning DMA off. I’m almost ready to take a bat to it and buy an $80 replacement, but I’d rather not if I don’t have to.

Any ideas, maybe some kind of modified firmware? If so, how do I do it?
