nomadh, I'm probably a bit biased about this but I have to disagree with some of your post. Since the LiteOn 165x6S burners, LiteOn drives have been producing excellent results with most media and they even updated the 5S firmware to do most of what the 6S does, as well. My current 20A1H burns media up to 16x even better than my 165P6S and I get better results with these LiteOn drives than I do with my BenQ 1620, 1640 and 1650. LiteOn's learning strategy works very well and allows media to be overclocked, sometimes up to 400% and future media codes to be burned as well.
Yes in the past LiteOn had a very bad patch with some of their drives but now I think a lot of people would agree that things have changed.
