hi:
i have some burned DC cds
i need to make back ups of them
how do I do this?

i tried getting the files with iso buster then burn with nero,
It worked before most of the time, but now I forgot what settings i'm supposed to use. (I have a creative 8432 and i tdoesn't seem to work with cue/bin)

I tried CDRWin and it failed 100% of the time. The cds appear to be burnt fine but won't run.

I don't know about disc juggler Never tried it.
What kind of files do disc juglers use CDI?
If I have the actual CDs how should I extract CDI or whatever the format I need from it?
