burn dvd

i havent used fotomagico in years but have a client who wants a slideshow. i created a slideshow movie and exported it as a 1080hd to be burned to dvd and everything works great although the .mov file is 19 gigs. how can i make this file small enough to burn to a regular dvd disc? the slideshow just contains 375 photos and a 19 minute song so i wouldnt have thought it would be so large

Which version of FotoMagico are you using?
