We have Windows Vista and PowerPoint 2007. We have a presentation with embedded videos (.wmv & .mov). When we connect a Dell projector we can (of course) view all the slides on both the laptop and the projector, but not the embedded video.
When we press F8 the view switches between laptop only, laptop only (again), projector only and back to laptop only.
How can we get the video to play on both the laptop and the projector simultaneously?
The weird thing is that this used to work!
One other note - I've followed some internet instructions (example) but the Change settings button on the Troubleshoot tab (on Multiple Monitors) was disabled!
