I was playing a movie in Netflix through my Chromecast, then I wanted to play a Youtube video. The movie was running when I hit the cast button in Youtube, but the video didn't start playing immediately. Should it take over when you play a new video? Or does it get set up as some sort of queue or playlist? Also, is there a way to "close" an app? Netflix has a stop button as you're casting your video, but it hasn't been responsive. I heard from someone in another forum that each item you send to the device should instantly kill the currently playing video. Seems like that's my answer, but let's see if we can confirm this. Thank you.
