I switched and bought my first Mac in july. I bought a 20" Intel iMac. So far I am loving it! One problem I am having though is burning audio CDs. I am using media that when burned on my PC all my players have no problem reading. When I burn on the iMac only the iMac will read it as an audio CD. I have tried many ways of burning iTunes, Disk utility, 3rd party apps. Nothing but coasters that the iMac can read. The CDs I am using are Memorex, Does the drive not like them? I have seen other post on the net were people have said they have had problems with the Matshita DVD-R UJ-846 with firmware FB2U. This is what is in mine. Help? Hints? Ideas? Thank you in advance.
