To edit a Windows Media Encoder settings file

1. Start PowerPoint. On the Tools menu, point to Windows Media Presenter, and click Edit Windows Media Encoder Settings File to edit an .nse file.
2. The Open Windows Media Encoder Settings File dialog box appears. Select the .nse file you want to edit, and then click Open.

   The Windows Media Encoder Settings dialog box appears.
   

3. If you need to change to another computer running Windows Media Encoder, in the Encoder box, type the name of that computer. If Windows Media Encoder is running on the PowerPoint computer, type localhost.
4. If you need to set a new Base URL, in the Base URL dialog box, type the URL. The Base URL is important because when you move from slide to slide in the presentation, Windows Media Presenter appends the name of each image to the URL and then sends this URL as a script command to the client.
5. If you need to change the image format, select the format from the Image Format list. This must be the same format as the one in which you exported the slides. JPEG is recommended for higher-quality images.
6. Select Ignore errors from Windows Media Encoder. This allows you to continue your presentation regardless of encoding errors. If this is not selected, the Microsoft PowerPoint presentation ends if Windows Media Encoder fails.
7. Choose Start new Windows Media Encoder if you want Windows Media Presenter to start a new Windows Media Encoder session. Select the Windows Media Encoder configuration (.asd) file that you want to use with the presentation.

   Or, choose Connect to running Windows Media Encoder if you want Windows Media Presenter to connect to an existing Windows Media Encoder session.

   If you choose to connect to a Windows Media Encoder that is running, you can select Reconfigure using ASD file to change the encoderÆs configuration settings.

8. To apply these settings to the open presentation, select Use this configuration with the current slide show.
