I'm noticing most videos I want to stream on my Chromecast don't have a cast button. Mostly i'm assuming the buttons are disabled from the carrier for licensing reasons. I usually find the video and cast via Chrome and make the video the same size of the video and my TV looks generally fine. Anyone have any idea to force the actual cast function like casting a YouTube video? I even have trouble with casting my SlingBox (not the same as SlingTV) app to m Chromecast even though its supported. My best educated guess it a signal strength issue but this seems to be a common issue known by the SlingBox community. I have written and found articles again and again about this. I have found work arounds that are stable but super annoying for the average user.
