Youtube is almost there =) actually is fully done ( streaming videos ) but there seems to be a bug with mplayer that some videos fails. We are investigating.. but the plan is to have it in the next big update!

About the save the videos, that was the goal, but we cannot stream / save at the same time at the moment. It seems that the way mplayer streams doesn't let us do that. Of course people will be able to download it using the future videocast feature but we are not going to dive into this right now.
