If you're trying to burn an image, DJ should recognize the settings by its own. You shouldn't need to change anything...

Anyway, these are the settings I use :
_ mode = audio
_ offset = 0
_ block = 2352
_ toc = CD-DA
_ add post gap = checked

But I'm almost sure it's not the good settings.

If DJ says it's unable to detect CD format, you're bound not to use a good version of DJ (try to look for a newer version).
You should try to open your image with CDMage. Try to look for corrupted data. Maybe your image is corrupted...
