Our 6.0 release has greatly improved the speed of screen updates to the point where a normal-sized YouTube video can show almost every frame assuming you have decent upload speeds.
In an upcoming release, we are planning on providing a streaming video option which should further improve the smoothness of streaming videos.
Note that when you are presenting and streaming videos, you should also choose the Tools | Start to share my computer sound with attendees. When sharing your computer sound, at least one participant should join by using their computer mic & speakers.
