If every time you try to play a cartoon it says "the specified stream type is not recognized," or you have problems seeing or hearing the content, then you might need the newest Windows codec (the compression algorithm for the media file). Download the Windows Media 9 codec from Microsoft.

When you first attempted to install Windows Media Player, you might not have had the necessary permission to install software or your Internet security might have been set to "Medium" or "High." This prevents the codecs from being properly installed. Change your Internet security to "Low" during the installation process, or see your technology coordinator for proper installation.

Note: Please make sure to check with a parent, teacher, or adult in charge of the computer before downloading any software or changing any settings on your computer.
