I put one video on slide but it don't played.

Assuming that you tried it out by clicking on the Play button in the Tool Bar, did you then click on the movie to start it? The default is to "Start movie on click."

The other way to test your movie is to click Format in the Tool Bar and then select the movie by clicking on it and then click on the Movie tab. You'll see a set of Controls that can be used to Play/Pause the movie etc.

If the movie still won't play for you, we'll need more info such as the suffix of the movie file (.mov. .mp4, .m4v etc.) what app produced it or where it was downloaded from (URLs will help) and so on.
