So the settings that got the most consistent results are listed below:
First clear OPC in EEPROM power cycle the drive and then try these settings
IMGBURN SETTINGS:
Layerbreak: Calculate optimal
OPC=OFF
EEPROM SETTINGS:
SB=ON
FHT=ON
OS=OFF
OHT=OFF
They should give you a nice stable burn on MKM003 with Singapore discs
Important: You should only Clear OPC and power cycle the drive before the FIRST burn, on every other occation you should not touch any settings, one of the reasons for these tests was so users didn't have to mess about with their drive settings before each burn.
Also With Smart Burn enabled the drive will memorise the last (EIGHT) burns and after this time will formulate a write stratagy best suited to the media, so if your getting slightly erratic but still decent to not acceptable, this is your drive formulating it's write stratagy so please perservire with the same settings and burn some more discs. (This is also evidenced in the scan results made by LIGHTNING UK!) If you are getting terrible results with these discs it is likely to be your drive.
In addition these burns can be done under the normal running conditions of your operating system, forget talk of running in safe mode and clearing processes, neither are applicable here. I know this is is a slightly contoversal view so I am going to Quote LIGHTING UK! on this very subject.
