Neither the floppy/usb images would work on a CD. The image has to be specifically made for a CD. Converting to CD would be a lot of work and I have no time to do this. I've never done it before either so I wouldn't know where to begin.
Unfortunately I can't think of a solution to your problem. You would have to find a proper .iso image or ask someone with experience to help you out.
Sorry...
Is there a reason why you want to use PAUD? There are many, many other images made for CDs.
GParted live CD may be for you: http://sourceforge.net/project/showfiles.php?group_id=115843&package_id=271779
There is also the Ubuntu installer CD.
