LG GH24N95 Firmware Edit

I want to slow down my dvd writer. Now it writes at 8x as the slowest setting. I’ve tried to dump the firmware with Mediacodespeededit from the drive & the LG Flasher Executable. I’ve had no luck. Could someone tell me some other way to do it that I haven’t tried.

There is no known way to alter the way the drive performs.
