Bottom right is the option to "watch on youtube" - that needs to go...
Have you also tried turning off video information as well?
Um, where is that setting, I don't see it?
This doesn't make sense:
it prevents hyperlinks on the video.
because if anything "prevents" hyperlinks, I shouldn't be able to go anywhere from the video, right. Now currently that's NOT the case, and prevention is exactly what's required.
Just to be clear - the video is to be isolated so that it becomes irrelevant where it's hosted or being played from whereas we know it happens to be youtube.
