Awhile back, I posted about an issue I'd been having with a G4 Mini not burning -R DVD media. I got some time to sit down with apple tech support about a week ago. what we did led to a Genius Bar appointment, and that resulted in the replacement of the SuperDrive. I don't know exactly what the problem was — dust, bad laser, etc, but I'm pretty glad to have my Mini back and at full functionality with respect to that drive. I have 2 minis and I like to burn 2 copies of everything; nice if you have 2 machines capable of burning 1 copy each. thot I'd let the group know how it all turned out. and thanks to those who responded to my original post. nk
