A method and system for switching media streams of a video in a client system. A first media stream of the video is played in a SHOW mode in the client system as the first media stream is received from a content providing system. During playing the first media stream, an environmental change is detected within or adjacent to the client system and in response, a switch is made from playing the first media stream to playing a second media stream of the video in the SHOW mode as the second media stream is being received from the content providing system. After playing first media stream is paused, the switching may occur upon matching timecodes distributed in the first and second media streams, by transitioning playing the second media stream in a HIDE mode to playing the second media stream in the SHOW mode.
