I also can say the same thing about LiteOn 1693s, I have close to 10 drives, but this one was giving me a lot of problems with any type of DVD+ or dash, unfounately I painted the front panel to match my silver setting, and I cannot return it so I replaced it with BenQ 1655, I am sure there are a lot of people who are happy with LiteOn 1693s, but mine is not good, at least with DVD burning. However, It was a very good CD writer. My LiteOn DVD-ROM and CDRW drives perform very well. But, when it comes to DVD burning my BenQ 1620 and specially 1640 are outstanding, don't know about my 1655 yet, but so far it looks promising. I also have NEC 2500/2510 and NEC 3500 is a very solid all around drive. I have learned that when almost anything you buy, the best bet is to go with the model and not the manufacturer's name.
