method for copying self-bootable backups??

[jergrad]

i'm having trouble backing up existing self-bootable backup games. i've tried direct cd to cd backups on discjuggler and NTI, however, the cd player appears when i insert my backup in the DC. i'm able to copy any non-bootable backups fine, this problem just arises when copying self-bootable backups. any help would be much appreciated.
