I have been using my NEC 3500 with the patched 2.1A firmware for months now with mainly Datawrite media and usually with no problems. Recently I started to get lots of coasters - usually in the last 10% of the disk.
I have tested the burns with DVDinfo Pro and am getting horrible results. With the Datawrite DVD-R Printable (not full face) the Pi-PO burn is excellent up to about 3GB and then spikes dramatically up to a PI value of over 1200 for the remainder of the burn.
The Datawrite Titaniums full face are not much better - same spikes at around 3GB and then up to a PI value of around 800. These can be read OK by my lounge player but I am worried they will decay and ultimately become coasters.
Have also tried on my Pioneer DVR 108 v 1.1.8 rip lock patched firmware - same problems.
Anyone else experiencing these issues with the above combinations?
Any other media choice suggestions that work well with the NEC 3500?
I can't seem to find a patched version of the official V1.20 for my Pioneer - anyone know where I might get one to see if this solves the problem.
This is SO annoying as I thought the NEC 3500, Pioneer 1.08 and Datawrite media were considered as good quality and good combinations.
