Problems with Fireburner

I got an audio as well as an ISO. I'm kinda new at this so I don't really know the difference between the self-boot and if it needs the boot disk. I used to book disk to see if it works but it didn't. I know when I downloaded the files it was 4 rar files and when I used winrar it gave me one cdi. My dreamcast took it as an audio CD. I tried just about every way to burn it. DJ2 kept freezing in the cache no matter what mode or settings that I changed Nero wouldn't work. I don't how to change the cdi into a CCD for CloneCD. Could you please help me. All these failures are pissing me off. Thanks
