On intel macbook dual 2Ghz with Matshita DVD-R UJ 857 drive
Trying to burn DVD with toast titanium or Mac Book's built-in software will throw:
medium error, sense code = 0x73, 0x03
peripheral couldn't calibrate power of the laser required for medium
Some DVDs will actually work, but others won't.
What calibration means do I have to be able to burn on unrecognized media?
