What is status of YouTube playing? For past few versions if I add YT link (by right mouse button - add url) I get error message :
"
Invalid media file:

http://www.youtube.com/watch?v=(I tried with many addresses)
---------------------------
OK

youtube-dl from https://rg3.github.io/youtube-dl/download.html works perfectly [exe version] so I guess this is Mezzmo error or still not available feature.
