My Nero has been running ok of late and i haven't tried doing a burn for a few weeks until today when i've had a few failed burns due to a power calibration error. I'm not sure what is causing this, can anyone have a look at my failed burn log and provide advice? I'm using Verbatim so i'm pretty sure its got nothing to do with my media. I also recently corrected an error with my WNAPSI.
