Gamez Won't Burn Using DJ anymore.

Hi, I have successfully burned 4 dreamcast games so far, but now disk juggler just doesn't seem to want to work. It probably only writes about 40k then spits the blank cd back out. My coaster pile is just building faster then the game pile. Does anybody have a solution for me. IT WOULD BE GREATLY APPRECIATED. P.S. I have a Hewitt Packard cd burner, if it makes a difference?
PLEASE HELP>>THANKZ<<
