Buslink (Lite On rebadge) less than six months old appears to be on the way out. Drive functions perfectly except for burning. It has started making lots of coasters and when a disc will actually load some (not all) of the tracs sound like crap. It blows my mind that some sound awful but others sound great. Nero reports that the burn was successful and reports no problems from the error check. IMO that only proves that the error check isn't worth crap because the disks sure sound awful and the source material is fine. I have tried Nero and Musicmatch and three different brands of media - nothing seems to work. The software and media perform flawlessly in another (older) burner in another machine and on the dvd/cd writer in the same machine. That seems to finger the Buslink (Lite On) burner as the problem. Anything else to try before replacing the drive?
