Re: Playing videos from a PC to a data projector
Sometimes you can get problems like this if the resolutions on the laptop and projector aren't matched. Some laptops use widescreen displays with unorthodox resolution settings. If you then try to get this image onto your data projector it won't accept this setting. Setting the laptop to 1024x768 might solve this.
Another thing to try might be to go to your display driver settings, and disable 'hardware acceleration'. This is what CBLong is explaining, the hardware is used to build the image, and disabling this setting forces Windows to render the image as a normal graphic. CBLong: This will also allow you to take a screenshot from a video (performance is affected with this setting, but that's not important for the screenshot).
