I dont know WTF nero is behaving like this. I recently got a Liteon drive 40X writer. I have burnt CDs at that speed no problem at all using latest Nero.
Recently I noticed it aint been burning @ 40 but @ X12. I thought at first it was the CD so I used different ones.
Anyhow didnt work, so I reinstalled nero still no good.
I ran the program that coems with nero infortool and it reported max speed as 12X.
What I did then was uninstalled incd and reboot surprise surprise nero infotool report max 40X. I tried burning and it worked @ 40x last night.
I never rebooted since. Today I ran nero and it reported max burn to be 12X and neroinfo the same. Yet I havent rebooted and installed incd. I havent changed anything even using teh same unbranded disks which were burning okay @ 40.
