Among all the minor bugs, and issues that are in Leopard, there is just no excuse for this shoddy piece of coding! I needed to burn a DVD. No problem! I entered my blank disk, selected the file and clicked burn. But then it happened! "The device failed to calibrate the laser power level for this media." Is it a hardware problem? Nope!! It turns out to be trashy code. To fix the problem, you go to system preferences > international and have to select US English, and restart your computer to burn a bleeping DVD!!!! That is just rubbish!! Apple's quality is getting worse and worse with every new product.
