OK, I really need help. I have a LG GSA 2166D burner and a HP DVD Writer 640B. Windows XP SP3 Until last week I had no burning problems, now all of a sudden, I can't burn a cd, I can burn dvds. This is happening on both drives. I reinstalled my drivers for both burners after uninstalling in safe mode, i uninstalled the secondary ide channel in safe mode, i then reformatted my hard drive, reinstalled windows and I still have the same problem. I've tried various discs, I've tried Roxio, Nero, Ashampoo and just about every other type of software and I just can't seem to get it. Any help would be greatly appreciated. Thanks in advance!
