Working with regular videos, but, sadly, isn't working (playing a 4 second buffer, then stops - like a regular player, if you feed the .aac YT link into it) with streams.
I needed it for music streams only, so I guess I'll have to use the old "workaround" - choosing the 144p video quality, to minimize the ping impact. =)

Works also good at Android phone. Easy on - off from the options of the browsed Youtube page. Great option to save data usage when needed.
