As of today May07,2013 it does not worked. Worked splendidly until yesterday.

It worked until yesterday. Starting today I tried a few URLs just to be sure and they all came up with only one format i.e. MP4 360p, clicking on more...did nothing. I am including just one URL here so that you can look into it: http://www.youtube.com/watch?v=JJqRqUyRsKY.
