I am using Photostory Deluxe 2020. I copied my slide show onto a DVD and also onto my computer in MPEG-4 format. My slideshow is 6 minutes long and in both versions a 90 minute slideshow was created. It does not stop at my last slide. The is nothing beyond my last slide but I do notice the volume curve continues even though the music ends. This has not happened before. So it creates this huge file for a short slideshow.
