Blanking seems acceptable if your video is running in some window somewhere, but if it's running fullscreen then it sounds like a bug. I recommend you report it as such (against the specific video player you're using). I suspect the behavior may depend on the DE you're using and things like that, so you'll probably want to include that in your description of the bug. Stefan
