First off, I'm on an iMac, not a PowerBook, but I don't think that should matter (Snow Leopard 10.6.8; Matshita UJ-85J drive; FCQA firmware).
My issue is the same. When I try to burn data to a DVD via the Finder or any third-party software, whether the disk is Sony or Memorex, -R or +R, 1x or 8x speed, it eventually ejects the disk with the error, "The disc can’t be burned, because the device failed to calibrate the laser power level for this media." Keep in mind that I can read DVDs just fine. And I can read AND write CDs.
The first time I tried to burn a DVD after I got the computer (which had been a demo model at an Apple Store), it was hit and miss--some burned, most didn't. I just thought I had gotten a bad batch of disks and returned them. I haven't had a need to burn to a DVD since, a year and a half later, and here I am with that error message.
I've tried everything suggested--reset the PRAM, ran a cleaning disk (several times), shot compressed air full blast (several times, up and down), swiped with a cleaning cloth-wrapped credit card (several times, my personal favorite for creativity!), and what people refer to as "the language thing." So far, No good.
Any NEW ideas out there re: this problem?
