[v6 General Discussion] EW6 & PowerPoint with Embedded video
To use video or audio in a PPT in EW successfully, you will need to make sure the presentation is created on the same computer that you're projecting with, or make sure it was created in PPT 2010 or newer. Make sure in EW6, you have the default option set under Edit, Options, Advanced for EW to use the PPT application (box unchecked). You will also need to have the video set to auto play when you go to that slide. There won't be an option in EW to start a video manually in a PPT file.
