Imagination creates 0B large VOB file

[Richard Riley Gress]

Trying to create a VOB file with imagination. The slideshow is 14 slides long, with a crossfade between each slide, each slide lasts four seconds. The media is an assortment of .jpg files. The project is NTSC. I select "16x9 Widescreen" before exporting to VOB. The process continues as normal, and the result is a VOB file 0B large that will not play. I was hoping for a large VOB file that would play.
