Sorry if this has been answered elsewhere. I cannot seem to find a definite answer to my question! I'm a complete Apple virgin other than my 5s. I've been given a iMac G5 (20'', 2GB RAM, 500GB HDD - upgraded). Anyways, my question is this. The superdrive is supposed to burn DVD-R & DVD+R, yes? Well, I've been trying with no success to burn something in disk utility.. I have a pack of brand new TDK DVD+R disks, alas none will burn.. I get errors ranging from: laser power calibration, medium write error, or the drive can't respond or something? I tried Toast, same sort of thing, and error of 0x03 iirc comes up! It burns CD-Rs perfectly, reads burnt DVD-R & DVD+R and plays DVDs great.. I've tried the compressed air in the drive trick - no luck I've tried something about the international, changing language or something - no luck Only thing I haven't tried is a different brand of DVD. But I'm not holding out much hope to be honest. Anyone else had this issue, and anyone found a solution? It's a Matshita drive and I'm running 10.4.11 (trying to update to 10.5, but can't burn the bloody disk!!) Cheers!
