If you have added music to the slide show, it should be on the DVD.
Use iMovie to create a slide show. You can add all the transitions and other neat stuff AND add a text slide
Using iPhoto 8.1.1. & iDVD 7.0.4 OS 10.6.3
Music :If I burn a DVD from an iPhoto Slideshow, will the music in the slideshow be on the DVD ?
Text Slide :I want to add one or two slides which just have some text on - probably - a black background, how can I do this ?
