Liteon DVDRW SOHW832S 8X Burner, it's about 1 & a half years old. I had xp pro SP2, nero 6.6, clone cd 5.9, dvd shrink 3.2, dvd decrypter & had to format & reinstall xp home SP1 (I don't have xp sp2). Now the burner doesn't recognize some dvd-r 's that it used & worked fine when I had xp sp2. It would just spin & blink make noise and says insert a blank.......but sometimes it burns on the same dvd-r that it didn't read previously!!! So, is it time to get a new burner? XP SP2? Or inferior blanks. Thanks!!!
