Help with Selfbooting Games

I have followed every thing in big popas post.
I have been using dj 2.0 to try and copy my selfboot games. I uses cd to same recorder. when the game pops out I puts in the blank cd and it burns for about 2mins and every time different error messages come up.
If some one could help me I would be very greatfull.
Thanks Sir Delvin
