    if i plug my tv in to my macbook using an thunderbolt to hdmi cabe, i cant quite get it to do what i want. i want to be able to open a video, drag it across to my tv and full screen it. this works fine but then as soon as i move off the desktop on the macbook the tv also moves as well. i definitely dont have the diaply mirrored.
    can i not surf the internet on the laptop with a video on the tv? it worked fine on my old windows laptop :(

    OSX sucks for multi displays.
    If you full screen an app, the second display pretty much becomes useless.

    Full screen is "less functional" in dual screen setup since Lion. It turns a second monitor into a gray wall. Not very happy with it. You just need to watch your video in a maximized window (not full screen). We are waiting for Apple to "fix" this but I doubt they will do soon.

    Use a third party media player like VLC. You can drag the window over to your HDTV, maximize the window and play it while working on your MB. However, if you switch Spaces, the HDTV will switch Spaces too.
