The DnD Sanctuary

Hi all,
I have found a script that can disable html5 media player and enable again flash player on youtube to watching video at 1080p, until html5 media supports is complete.
The script can be found here: https://productforums.google.com/d/msg/youtube/CUaTWvKhAuE/q6P1m1kpAwAJ (https://productforums.google.com/d/msg/youtube/CUaTWvKhAuE/q6P1m1kpAwAJ) but to works on otter [otter-browser-win32-weekly188 WebKit backend] the script needs for some changes

// ==/UserScript==
(function() {
window.setTimeout(function() {
  var embedFrame = document.createElement("iframe");
  //embedFrame.src = location.href.replace("watch?v=", "embed/");
  embedFrame.src = location.href.replace("watch?v=", "v/");
  //embedFrame.style = "width: 100%; height: 100%;";
  embedFrame.setAttribute("width", "100%");
  embedFrame.setAttribute("height", "100%");
  var player = document.getElementById("player-api");
  player.innerHTML = "";
  player.appendChild(embedFrame);
},
3000);
})();

Unfortunately, It brakes the fullscreen mode.

Thanks again to Emdek and all the guys behind this awesome browser!  :D

Simple updated to have a link to fullscreen version of the video and some other improvements
