fotomagico 5 pro burning problems to toast

Have installed FotoMagico 5 pro from a bundle when we purchased toast titanium pro version 17.Having edited a film in FotoMagico it will not burn to a blue ray dvd. the message we get is MacOS error 9999. If we burn the same film from IMovie at 1080p into Toast we have no problem. We would prefer to use FotoMagico as it is a much better editing programme than IMovie. Any help out there would be very much appreciated as we have been struggling for sometime.
