Click here to view full specs.[/qanda]Burns O.K. but wont recognize what it has burnt.“Raw Disc” when properties clicked.Plays on other pc or DVD player. Removed and re-installed.Worked until next re-boot. Hp’s advise try on other computer.Other computer has cheap Lite-On works fine. Store where purchased swapped previous LG for this.Didn’t even ask what the problem was.Could probably swap this for latest Samsung with cash difference.But why wont they or hp help solve the problem?
