I have a PowerMac G5 and I'm having trouble making music CDs with it. When I create the CDs they play fine in the Mac, but it doesn't produce CDs that are fully compatible with other CD players. For example, my Aiwa CD player won't play them at all, nor will they play in my RCA. However, my PS2 will play them, and they'll play in my Car stereo (Alpine deck) but if I try to skip tracks it takes the player a long time to find the track, as though it's having trouble reading the disk. I hate to say it but my windows PC burns reliable CDs everytime. I use Sony CD-R media rated at 48x. I've tried with Toast 7 as well as burning from iTunes, and I've tried turning down the burn speed to as low as 24x. Anyone else have problems burning audio CDs on their Mac? Thanks.
