My benq dw 1640 has suddenly started to only burn TYG02 media at 4X or sometimes only at 2.4X!!!
I have been running the L version of the firmware and all had been fine and I could burn the media at 8X no problem with Overspeed switched on.
Now for no apparant reason it will not burn at 8X anymore!
It is very strange that I made absolutely no changes and now it will not burn as it did before…
Anyone know how to fix this?
