Problem: I am trying to use Active Presenter (free version) to capture video of a TV show on the Sling application on a Windows laptop. Note: I am running the Sling application program that is installed - it is not run within a browser. I am using the Record Video function, then I export to a video file (MP4). When I run the resulting MP4 file, only the headings and the audio are captured. The rest of the video is black. If I enable the Closed Captions on Sling, also the Closed Captions are captured, but never the video images!
Here is screenshot showing only black screen (no header, no closed captions, and no video images) - this is what shows when there is no header, or closed captions displaying:
