Hello, I have a Sling Box 500 that works great. I can pull it up on my Android phone or tablet just fine. I see the Cast tab now and am connected to the same network as my Chromecast. I hit cast and select the Chromecast. I see the Slingplayer logo come up on my TV with the Chromecast in it. The minute the screen goes dark on the tablet, and says "You are currently streaming to Chromecast", the image on the TV goes back to the Chromecast Screensaver. Any thoughts on why this is happening and how to fix?
