backup of a backup?

hello-

i know that it's possible make a backup copy of a backup, however, i'm stuck. I tried everything from extracting the contents of the backup with BlindRead and DDump and they seem to bind both audio and mode 2 tracks together into 1 big audio track! then, i used discjuggler to create the cdi image and converted that to nero, it created the image ok, but it still doesn't burn correctly. what should i do? i have an hp 8000 and an hp 8100...both read data/audio...please, if u know anything that could help me, please e-mail me at officer####@ureach.com ...any info would be greatly appreciated! thanks!
