Thanks for the suggestion. I will download imgburn and give it a go.

00010,

I downloaded snowosx universal 3.5 as I could not find version 3.6 and encountered the same problem. After booting off the dvd, it would always crash when loading system libraries and then a hard restart would follow. I tried setting different flags such as "-v cpus=1" & "-v busratio=20 cpus=1" with no luck. I will try reburning the image at a slower speed and see if that makes any difference. Thanks
