the burn cd option will burn presentation to cd so that the user can play them
on every dvd player

why is it good:
- this is a very elegant way to run presentation
- if you perform a presentation, you don't have to come half hour earlier to
make  sure that everything is working, just put the cd in the dvd player and
click the on button.
- there are a lot's of dvd players so you are solving the format problem
- this is the pdf of the presentation
- the user can use the dvd remote control to navigate the presentation

how you can do this:
dvd players can do two things 
1. play video (you don't need this)
2. navigate in the menu with the remote control (languages, subtitle...),
this feature is similar to navigation on presentation

if the user select this option (export presentation to cd to play on dvd)
openoffice need to create an "auto menu" to the presentation that the user want
to burn

how to run:
openoffice impress>file>export>burn presentation on cd to play on dvd
