I am simply trying to burn a hard copy of my fotomagico slideshow that I created through Roxio Toast

I am simply trying to burn a hard copy of my Fotomagico slideshow that I created to Roxio Toast Titanium 11. When I try to burn it, it keeps saying that the format is an unsupported format. Not sure why this doesn’t work since Fotomagico came with my purchase of Roxio Toast. You would think that they would be inherently compatible. Please help.

I used Toast 11 with no problem. I think it was shared to desktop as a ProRes video, and then sent to Toast.
