Don't know how to burn a disk but when trying to save to floppy, it says,
"not enough room."
Well, "not enough room" means that there is not enough space for
containing your presentation.
If there are a lot of audios and animations in your presentation, you
should send all of these to your floppy along with your presentation.
So the presentation will be a little big in file size.
You can try to convert your presentation to Flash with some third
party tools such as PPT2Flash (
http://www.sameshow.com/powerpoint-to-
flash.html).
The application can help you reduce your file size upto 90% of your
original file size, so you can send it to floppy. That takes up
smaller space.
Hope it can help you.
