I have a LiteOn LDW-851S and have not had any problems with it what-so-ever. I only burn DVD-R media because my Panasonic and JVC stand-alones seem to prefer these, in fact I'm pretty sure that the Panasonics will not play DVD+R (haven't really tried too much since DVD-R has always worked well). I have been thinking about buying a new, dual layer burner, but all I seem to find are DVD+R9 burners and media. Do they make DVD-R9 (dual layer) burners and media? I would like to stick with the LiteON brand as my current model has preformed quite well, but would switch brands if someone else made what I'm looking for. I know the price of dual layer media is still very high, and I will probably stick to burning single layer media until the price drops. My main concern is the compatability with my stand-alones. I don't think they will play DVD+R9 and I don't want to buy a dual layer burner now that won't work for me in the future. Any help, feedback, opinions, or tips would be greatly appreciated.
