By using "duplicate," I assume you do mean burn and not "replicate."
I find no previous threads or google searches that relate Encore and packet writing, except for references to other software interferring.
Try building to a folder, then create the image with ImgBurn. (You don't say; it is only for PC.) That may or may not help, but ImgBurn has a lot of options. See their forum for info. And send a donation if it helps.
