After reading through the threads on here about this burner I’ve decided to return mine. It is supposed to be a 4x burner for DVD-R, but I’ve yet to hear of anyone who’s achieved this. The new firmware makes no difference and the money I’ve wasted on burning coasters I could’ve got a Pioneer, so that’s what I’ve done.
From expensive Maxell branded 4x media through to cheap discs, it fails every time with DVD-R unless you drop to 2x (I bought a 4x drive, I want 4 x recording and so should anyone else who bought this drive). I bought the liteon because I have had their cd drives with no problems, but this problem seems to be widespread, many forums at various sites, everyone frustrated in the same way.
This machine does not currently do what is it supposed to do and therefore anyone with one should be entitled to a refund, certainly in the UK as goods must be able to perform as advertised.
Good luck to anyone who perserveres, but for me it’s just too hit and miss.
