Hello, I'm a new user to this forum and wonder if anybody could please help with a problem I have with my (now very old it seems) G5 Mac. I have issues with burning CD-Rs. It seems to be pot luck whenever I buy a pack of CDRs whether they will work or not. DVDs are fine but CDs is a nightmare. I've found over the years that Sony seem to provide the best performance but I've now bought two lots of 50 and none of them work at all. Verbatim have never worked but Sony always used to seem pretty good. I actually found I had a couple of old Sony ones and they worked perfectly and burnt with no problem. None of these new Sony ones seem to work though. I should point out that they do burn at 12x higher, but I need these CD-Rs to be 8X or less. The Mac tells me they can burn at 8x and 4x on the "about this mac" but they just will not burn. Do Sony CDRs generally only work at high speeds now? If so, what is a good make for burning at lower speeds? Many thanks.
