I'm impatient so I burned at 8x which is the fastest my burner does (and my media is rated at). It all worked out, and I've got 10.4.11 running on my Mini now. The last image I got worked out doing a raw burn in MagicISO despite the program telling me it was non-bootable when I analyzed it. Now I just need to figure out where to put the damn thing since my desk space right now is packed.
