I have tested the Al-Jazeera youtube stream in RoboB (using Internet Explorer 11) and it is working for me.
However, the only way I can make it full-screen is to use mouse emulation, because IE11 doesn't seem to support the youtube keyboard shortcuts.
But in this case, using a regular browser is fine -- Firefox or Chrome. If you want to have the video automatically go full-screen, you can use the keyboard shorcut "f".
*BUT* regular keyboard emulation does not work. Youtube keyboard shortcuts require DirectX, so you would need to enable the DxInput plugin.
e.g.
<?xml version="1.0" encoding="utf-16"?>
