DVD Internal error

I have prepared a slideshow using FotoMagico 4.4. I want to burn this to a DVD. Iused the DVD option in Sharing. The visual rendering and calculation processes were completed but then I received a message that there was "A DVD internal Error’ and that the material was "not a movie. How can I resolve this please?

I am not sure whats happened. Please try to export your slideshow to the Desktop using the normal HD export option rather than using the iDVD export option. Once the export has finished, please drag the movie file from your Desktop directly into your DVD project. Does this work for you?
