A snippet from the oooforum.org discussions:
If you use the OpenOffice.org presentation software's export to html option, then it will generate a collection of .png, .gif or .jpg image files of the pages you created. If you have updated Windows XP to SP2,you can use Windows Movie Maker to convert these to a movie. Subsequently, you can use a DVD authoring program like WinDVD Creator to put the movie on a DVD with menus.
File > Export...
File Type > HTML Document (OpenOffice.org Impress)
Select or create an empty folder to create the HTML presentation in. Accept defaults, except instead of using the default low resolution, pick medium or high.
Copy the images to a new folder.
Close OpenOffice.org presentation software and open Windows Movie Maker. The program is pretty straightforward. You can use the online help to figure out how to add images, time your slides and add music or narration. Save the movie as a high quality movie.
Use your DVD authoring software to set up the menus and to add the movie to your DVD project. Burn your DVD.
Some DVD authoring software includes a slide show tool. You could also try that instead of Windows Movie Maker to create your slide show. Microsoft also has a dedicated slide show program called Photo Story that is available as a free download as part of the "Genuine Windows" promotion.
