Thanks for your reply. This is the GUI i'm using:

I've been having the setting for writing back set to .scp: Amiga format (or something - i'm not in front of it right now)
I've played around with some of the other settings. According to changing some of the other settings when making it, i can get the Amiga to make different sounds and clicks etc as it tries to read the burned disk after i insert it into the Amiga drive. But the disk always fails to load. I've even had it spit back out a guru meditation at me from attempting to read it.
Considering the file plays fine in AF on my laptop, i've got to consider that the file must require a specific way of being burned back to disk for it to be readable by the Amiga.
