Ever since I purchased my Lite-On LDW-451S burner I have had no luck with updating the firmware, I purchased a bundle of cheap media from eBay and was having no luck at all getting any good burns, I decided to go back to the original firmware GSB6 and while the burns were still not good (crap media) they improved remarkably. I now only use my Lite-On for scanning as it will not even create a good burn using TDK (TTG02) media, now I burn with my Pioneer A07-XLA v1.21, and the scans on my Lite-On were coming out amazing, I had never seen scans like these before. Anyway, I decided to update the firmware on my Lite-On to the latest version (GSBC) seeing as though it was a scanner only now, but now when I scan my burns they come out crap, even the discs that first scanned excellent were now scanning bad, I put my firmware back to GSB6 and magically all my burns are scanning as before. So are my burns bad and I am getting unreliable results with the old firmware, or is it more likely a problem with the drive + firmware seeing as though the drive reads and writes bad when the firmware is updated. By the way all the discs actually viewed so far have been excellent.
