Solaris 11 downloads

 Again....I feel like an idiot but still can't get something this simple
working. I have downloaded both IPS images, cocatenated them together (on a
Solaris box), and created an iso with Nero. No dice...

I then downloaded the text installer, which is an iso also, burned it to cd.
No dice....

With both of the above iso images I recieve: "Bad magic number is disk label"
                                                                "Can't open
disk label package"
                                                                "Error:
boot-read fail"


One other sunmanager member hinted at the type of media I am using. I have a
DVD+R and he states I may need a DVD-R. New to me but I will try to find a
DVD-R.
