just wanted to check... I'm using the Lifesizecloud app... One of my users wanted to share a movie. I suspected this would not work very well, depending on bandwidth and location of where attendants are. Turned out to be true. There is firstly a lag and artefacted video. Secondly audio also did not pass. In my opinion videoconf is not suitable for sharing a movie. You need something which is typically meant for streaming mode, and which is basically one-way-direction like Office 365's video option.
