roVideoPlayer and GetInfo() for it's events

Hello!
I use roVideoPlayer to get more flexible control to it's interface, and I want also display dots as in roVideoScreen to show quality of selected stream for adaptive bitrate.

According to SDK there must be "Stream Started" event with Info field with necessary information. But this event never occurs.

And even if I try to use the event handler like this:

while true
	msg = wait(interval, port)
	while msg <> invalid 
		if type(msg) = "roVideoPlayerEvent" then
			info = msg.GetInfo()
			if info <> invalid
				videoBitrate = info.StreamBitrate
				print "Bitrate: " + Stri(videoBitrate) + "; Event: " + msg.GetType() + "; msg: " + msg.GetMessage()
			end if
		end if
	end while
end while

There never occurs events with not invalid info field.

So, how I can to get bitrate of selected stream?
