I have a double layer 16x memorex DVD burner its about 2 or 3 years old. I talked to them about a year ago and they said my DVD burner can support write speeds up to 16x. I got a 50 pack of DVD+R 16x but everytime I burn a file to those disc's before it even has the chance to burn it will come back and say illegal disc and eject the media........ I talk to memorex one more time about 2 months ago and they said the DVD burner has a problem or a lock on it to keep it from burning at that speed. they said they will not do anymore firmware updates. my quesion now is their any 3rd party firmware updates that can bypass this problem ? I don't want a whole spindle of DVD+R to go to waste. my dvd burner label <memorex DVD+/DLRWL1F16
