Strange...
Burning 1st session with DJ might take ages. I recommand you wait a little bit (maybe 30 minutes !!!) and see what happens.
I don't know *.ccd / *.img / *.sub images, but you should try to open all your non-working images with CDMage. Try to read these images, extract all the files and use Echelon's tutorial to make a selfboot copy. That's what I would do if I were you.
