I have a Lite-On 1693s and I can’t burn or play CD’s anymore. I’m using Nero 6 . When I try burning it would read from the source and won’t burn to the destination which is my 1693S the tray will just open and display waiting for CD, it recoginze it as a blank disk. Does anybody know what’s wrong with the burner? Maybe it’s dead? Or am I doing something wrong.
