Stop Sproutvideo playback

Has anyone been able to pause/stop an iframe-based SproutVideo playback from inside a Hype scene? I've been trying out ideas from here, but I'm at a loss:

here is a live-example:

the required id seems to be this part of the iFrame -URL:*thisNumber*709adcb31f19e5c6f8*stopHere*/cd8cf2e796aa69d3

you should simply copy paste the required code from there ...
