So I hook up my MacBook Pro to my TV to watch movies and play games. I used to use Front Row all the time, but that's gone. So now I just open my movies directly in quicktime player. But here's the problem: every time I try to put the movie into fullscreen mode, it moves it over to the primary screen in full screen mode. The primary screen is the laptop's screen. I obviously want the video to be full screen on the TV, the external. The window is on the external when I tell it to go into full screen mode. This seems like a bug in Lion. Any ideas?

I haven't tried it in Lion but it used to be that if you drag the QT window onto the second display it would go full screen on the second display.

Alternatively you could just switch the the external to be the primary display, but that won't help if you are looking to do things on the MBP while you watch films.

Apart from that, it wouldn't work, since full-screen mode in Lion blocks out all other screens with that infernal linen.

Normally QT Player goes fullscreen on whatever screen it's already on, like Waragainstsleep says. If it no longer does that, switch to a different player. I like Mplayer OSX Extended, or Movist or VLC, but you can also use front end apps for the QT framework. Like NicePlayer, Xinema, or XinePlayer.

The first 3 have setting in their preferences on which monitor to go fullscreen on. I'd expect the others to have that too.

I'm pretty sure the default behavior has changed in 10.7

Isn't that what I said? That switching to the external as primary would stop you working on the internal screen at the same time.

I took your comment to refer to the menu bar and Dock then being on the external display, not that the internal display would be blanked out entirely.

Try using VLC, it's never failed me in multiple monitor setups. I have the same issue with QT as you describe on my MBP, and I have the external monitor as the main one.

This has been an issue with the QT-player since Leopard days, at least.
