Audio and Video Problems

The Show Me sections in the lessons and the case study videos require that you have sound capabilities with your computer, including:

• A properly installed sound card

• Speakers or headphones

• Windows Media Player 7.0 or higher installed

If you receive errors when displaying the Show Me exercises or playing the animations or videos, there is probably a problem with the file associations for your .wma audio files or your .mpg video files.

To fix the problem:

1. Open the Windows Media Player

1. Click the Windows Start button.

2. Point to Programs. Point to Accessories. Point to Entertainment. Click Windows Media Player.

2. Click the Tools menu, and select Options...

3. Click the Formats or File Types tab.

4. Ensure that Windows Media Audio file (wma) is checked.

5. Ensure that Movie file (mpeg) is checked.

6. Click OK. Close the Windows Media Player.

If the problem persists, re-install the Windows Media Player from the Windows Media Player 7.0 folder on the MISource CD-ROM or download and install the latest version of Windows Media Player from Microsoft's Web site.
