My opinion of Liteys has always been , until I got my BenQ 1620 Pro . The only reason I say what I say is look at the following. I know that they are average quality discs, but this is my point. A burner should be able to do fairly decent burns, given that they are not feed total junk. Here is the log my 1620 Pro burn with DVD Decrypter
