Hi Bob, what do you mean with "their AV software"? the drivers of their video adapter? Or do you think of any other? And what do you mean with "feature"? to suppress the ability of making screenshots in general? Ever heard of something like this?

For my limited understanding this is related to the video/ screen buffer. I tried both LiveCode options with alwaysBuffer of my videoPlayer = true/false. Same result, black screen. This issue seems perhaps not to be only a LiveCode issue because creating a screenshot with other apps also only get a black screen from the video. In an older version of my program with QT videos and older machines (up to win 7) I also experienced this behavior on some rare machines and I found that turning the hardware acceleration of the video card to off fixed this issue. But since windows 10 there isn't anymore this option "hardware acceleration" in the properties of the video adapter, which you could turn off and I didn't found any comparable option. Has anybody perhaps any idea, what I could look for changing the video buffer behavior inside LiveCode or the system?
