Avoid a QuickTime playback issue in Keynote '08

While working on my slides for my upcoming "Best of Leopard Hints" talk at Macworld Expo, I ran into a very strange issue: embedded movies would cause my slideshow to come to a total halt -- the movie wouldn't even appear onscreen, much less play (though it appeared just fine on the presenter display).

After some googling, I found the (very odd) solution in this thread over on the Apple Discussions site. Open Keynote's Preferences, then click on the Slideshow section, and check (enable) the 'Allow Exposé, Dashboard and others to use screen' preference. Despite the warning below that option about affecting animation performance, this solved my problem: as soon as the preference box was checked, the formerly non-playing videos started working perfectly.

It seems quite counter-intuitive, but whatever the reason, I'm glad it solved the problem, as I was quite stumped!
