Ok,I have a macbook os x version 10.5.8 Processor 2.4 ghz intel core 2 duo Memory 2GB. 1067 MHz DDR3 I was using itunes for ages now lol. But i ran across a problem that is stalling me,i was trying to burn a Audio C.D. And it said: "The attempt to burn a disc failed.The burn Failed because of a medium write error." I put it on Maximum possible,24x and then i just tried 4x and it worked. But i do not like this at all! Does anyone know a solution for this i tried using Mac's burn program and STILL had the same problem rather frustrating. Anyone know how to fix this problem thanks.
