It sure does! You can move your player window from space to space. Get it out of the busy space with your email and chat applications and into a space all its own. When you go back to your mail and chat space, you will no longer see your TV, but you will still be able to hear it.
One thing to note is that there is an issue with moving the SlingPlayer window from space to space when you are watching it in full screen mode. After you move the SlingPlayer window that is full screen to another space, it will shift the whole image down about 30 pixels.
To get it back, just exit full screen by double-clicking on the video. Once you have done this, double-click on the video screen again to reenter full screen mode. It will then take up the entire space without being shifted down. |
