One major difference I noticed when casting a video for example from YouTube is that with chromecast, my TV turns on automatically for example and switches immediately to the chromecast input. So video plays immediately. Also if the TV is on and set to another channel. When I play a video on chromecast it automatically goes to the video on my TV.

Unfortunately this feature doesn't work with the MI box S. Does someone know if this can be enabled?

Am thinking of returning the MI box S, because of the lack of this feature.
