Agreed. As Pauli might say, physics without math is "not even wrong."
... I can watch the videos, but the player controls are unusable (clicking on them does nothing).
I have this problem too on Hulu and Youtube alike. I found that if I click and hold the middle button on my mouse and click the first button, I can use the controls again. Pretty ugly hack, I know, but it works! What's worse is that this bug comes and goes, and I can't figure out what's causing it. In fullscreen mode, the controls work normally again.
