[qanda]This thread is about the Lite-On SHW-160P6S. Click here to see full specs[/qanda]I just installed a fresh copy of Windows XP pro on my comp. Before I formatted my harddrive all of my DVD-Rs worked fine. Now ONLY my dvd-r's work and my SONY DVD+R rw, windows says, are all blank. I'm unsing nero 7. I had this same problem many many years ago and just took it as a loss and moved on. Now however, I have quite a few programs I need on various dvds. I reinstalled windows twice just to make sure it wasn't a bad install or something like wierd like that. I have installed windows before and didn't have this problem. why now? I even tried a firmware update on my DVD drive. Still the same result. Does anyone have any suggestions?
