export OO presentation as movie video

Hi, Not SuSE related, but I'm always amazed how many good advices one can get here :) I want to create a small titles for my home videos. I.e. I'd like to prepare some titles for every chapter I write on DVD. OpenOffice Impress is really suitable for what I want - some text and pictures, maybe some slideshow effects between the pages. Now, the question is, how do I export it to any type of video (movie) format, so I can encode this to mpeg2 to add it in the DVD? Or any other combination of applications/tools and how-to's to get there? Thanks Sunny
