-- I've had it for a long time. High definition videos are not streamed. When you try, your TV shows "choppy, choppy" etc. As far as I can tell, no set like this supports 1080p yet. Again, don't believe the casting ads you see. 720p is crap shooting, but it happens most of the time. In general, the smaller the video, the less clear it is, the more likely it is to send successfully. First, don't put too much stock in what the ad says about broadcasting what you're watching on your media device…
