having read over this thread to try and help again (seeing as you are posting in 2 threads the same questions). I looks like to me you are going at it like a bull in a china shop and rushing. There must be hundreds of guides on the net how to do everything you need to do. Its seems like you arent really taking in what ppl are advising probably due to the fact you are anxious to see the results of this running on your hardware. Which distro are you using at the moment? Have you confirmed it got a phenom compatible bootloader and kernel? Does it have your chipset kext on? These are some of the most important factors besides good media and reliable burning. MacOSX DVD is very sensitive to bad burning its recommended you burn at the slowest speed the media and drive will take.

P.S. Google is your friend!!!!
