I have been creating still slide shows perfectly with PicturetoExe Essentials 9.0.22 for several years. Right now though, I am creating a similar slide show but adding a few video clips mixed in. The video clips play perfectly but at the end of each, briefly freeze up for about a second, before advancing to the next slide. What is causing this and how to fix this? They are MP4 files and PictureToExe does ask to convert them to optimize them for smooth playback which I do. Thank you, Jeff Nadler
