For the past 2-3weeks i’ve put up with the fact that my burner has burnt at 1.6x speeds.
:a I am tired of this and have come to ask you guru’s for some help. 
I always restart before burning, and launch nothing but nero. Still 1.6x, DMA is enabled, AFAIK There is no ATAPI layers installed as I read there can be conflicts with ATAPI + NERO. If this isn’t the case welcome to correct me if I am wrong.
I disabled the IMAPI option in the administrative tools section also.
My buffer level when burning drops considerably from 89% to 13% and between. Granted this might be the adjustments of my burner but in the past usually stayed within the 70% to 89% or above range. Dont know if mentioning this matters but any and all information to resolve this issue is of the most importance to me as burning for me is a daily routine.
Any suggestions as to what can fix or what is causing the problems would be very helpful.
Using the latest 104c firmware + using sony DVD-R 16x + TDK DVD-R 16X Media. I will edit or reply with the DVDinfo on the Media mentioned.
