My pioneer dvd/rw drive has at some point in the last 2 weeks stopped reading some dvd-r disks my friend gave me. I have 6 dvd's, all burned on the same pc, with the same software,(I assume) on the same media, and at the moment my drive only will admit that 3 of them are useable disks. My guess is it has to be a software problem somewhere, because 2 of the duds worked a few weeks ago. i have tried everything i can think of, from the lense cleaner to re-installing windows,(scandisk, defrag, virus/spyware/adware scan,un- and re-installing the drive, updating the firmware, re-installing the dvd player software)and i'm out of things to try. So, anyone have a secret make it all better code i can type in, or some kind of voodoo curse lifter i can try? Arrrgghh!
