well, ive never messed with discjuggler because my burner hates it. or dj hates my burner?? i use a tool called cdi2nero to convert .cdi images into a nero image and then burn with nero 5x.
most ppl have said that the newer versions of dj and nero give problems burning DC images. they are DJ4 and Nero 6. to solve this, they just switch back to the old version, dj3.5 and nero 5. they have said the switch to the older version has worked.
so either use cdi2nero and burn with nero 5 or go back to dj3.5.
