I have six small clips (.wmv) inside a PowerPoint 2007 slide (for Windows). If I set all the videos to play automatically only the first one starts playing.
Any ideas how to make them play simultaneously?
In the Animation tab, select Custom Animation. Select all your videos, and choose Add Effects -> Media (something similar) -> Play.
Once you see the play animations in the animation pane, select all of them, right click, and choose With Previous in the menu.
