[Plextalk] Burning cd's with prs

Hi all, I have burned a project with prs, and I chose to burn it as a distrubution copy. So now, why is it that the project only contain an "ncc.html" file after building the book, but when burning the cd, both the "ncc.html" and also the "disinfo.html" file also are created. I thought its only one of the too wich get used at a time, or are the disinfo file only for cd's? Thank you for any help on this.
