Hi Yossi
Respect for your perseverance!
Hard to say if it should work with Google Drive or not - it is essentially a "special data cloud" but accessing it from your own app might require some permissions inlined with the URL.
Farzeen has given a YouTube example in that post, so I would try to get that working first.
Edit: You will possibly need to get that manifest modification done too.....
In your Screen2 Properties Palette, you are pointing to a link and not the underlying video, so the video will not be loaded - as Farzeen has already explained.
