Burning Back-ups of Back-ups with Discjugglar

[mykel]

I am new to this , any significant information would be greatly valued.

I would like to know if it is normal for a burned copy of about 600 mb to take longer than 2 hours to duplicate, using Discjugglar.
I believe when copying a game from the cd it creates a temporary image and then copies from that image into a new cd. But is it normal for the creation of the image to take more than 2 hours to create. This is what happened when i tried to copy a copy of sf3, fpd...etc
