I had actually thought about that, i.e the strategy of burning 8x media at 2x by and must admit that is the reason why I let the the LG4160 do its stuff and burn a disk at 4x as opposed to swapping drives.
However when comparing this disk burnt at 4x on the LG with one burnt on the NEC at 2x in Nero CD-dVD speed and the disk quality tab they don't compare. The NEC 2x burnt disk is way better to the point it coudn't be improved upon whilst the 4x burn is a bit of a disappointment.
Whilst I never burnt a Ritek G05 (8x media) at 4x to compare once again all the disks I burnt at 2x were excellent as well. Granted all the 100+ odd Ritek G05 disks that I have burnt are all disintegrating after not even a year (NEVER EVER AGAIN will I go near Ritek) but the fact remains they all burnt well at the time.
I have subsequently moved from A302 to A303 firmware for the LG but unless somebody says this is going to have made a wonderous improvement on a 4x or 8x burn making it as good as the NEC's slower 2x burn I am really happy with the slower speeds - what I am putting on the disks took hours (literally)to do - what's another few odd minutes.
I must admit I always thought that the burn speed permited by a drive was tied in with its firmware as opposed to any burning program which is the reason why I was asking what the NEC 3540 Firmware was saying for this Datawrite Titanium 8x media. I want to be able to stick with this 2x game plan if my old and well used NEC 1300 went to silicon heaven.
