sorry this might be too much at one time.
yeah at default for now is best, mostly i like to have the SB and OHT set.
be sure to save all of your create disc and quality scans so you will have them for reference. be sure to name them appropriately so you will remember what settings, speed and media you were using.
if you really want to mess with smartburn options there is a better [in my opinion] program called Settings Utility for LiteOn Drives
here is FastBurn, Enhanced OverSpeed & Enhanced OHT Firmware
there is a small tool called SetJitterSpeed this way you can control the speed of the jitter testing during a DiscSpeed quality scan.
its going to take hours of reading and testing before you really get what you want out of this. ive wasted many, many hours, days, weeks, setting different SB functions, using different speeds, different media all with different firmwares to decide how i like it set.
please go here and do alot of reading
now my main burner is a Pioneer and i have no control. thank god. so i just buy two different medias and use 8x for both.
but for a while i was still changing burn speeds and strategy swapping.
