When you embed a Windows .avi file as a Media Player object in a PowerPoint presentation, it plays in a window instead of full screen, even if you select the Full Screen option. To see the Full Screen option, click Multimedia Properties in Control Panel, and then click the Video tab.

This behavior occurs even if the Play In Client Document option is turned off in the media player properties.

There are three ways to make a media clip object play full-screen in a slide show. Method 3 is the only one that works with Windows NT.

Method 1: Resize the .avi File to Fill the Screen

1. On the Insert menu, point to Movies and Sounds, then click Movie from file.
2. Select the desired .avi file, and then click OK.
3. Use the resize handles to enlarge the movie until it is the same size as your slide.
4. On the Edit menu, point to Video Clip Object, and then click Edit.
5. On the Edit menu, click Options.
6. Click to clear the Control Bar On Playback and the Border Around Object check boxes.
7. Click the gray area outside the slide to exit.
   
   The media clip should now play in full screen instead of in a window. The size of the object in the screen is dependent on the video resolution.

Method 2: Insert the Media Clip as an Icon

1. On the Insert menu, click Object.
2. In the Object Type list, click Media Clip.
3. Select the Display As Icon check box, and then click OK.
4. On the File menu, click Open.
5. Select the desired .avi file, and then click Open.
6. On the Device menu, click Properties.
7. Click Full Screen.
8. Click OK.
9. On the File menu, click Exit And Return. Click Yes to update the object.
   
   This creates an icon on your slide. When you click this icon during the slide show, the Media Clip will play full-screen.

Method 3: Use Action Settings to Play the Media Clip

1. Create or select a drawing object, such as a rectangle.
2. On the Slide Show menu, click Action Settings.
3. Click Run Program.
4. Type the path to Mplayer.exe followed by the path to the .avi file you want to play, like this example:
   

          C:\Windows\Mplayer.exe C:\Videos\Movie.avi
   						

5. Click OK.
   
   When you run your slide show and click the rectangle, the Media Clip plays full-screen.

These instructions apply only to embedded Video for Windows files. Media Player can embed media objects of any type for which a Media Control Interface (MCI) driver is installed in Control Panel.

Each type of media has a different set of options. To locate the options, click the Edit or Device menu in Media Player.
