You've encountered an error message C00D10D1 while using Windows Media Player. The following information might help you troubleshoot the issue.
CODEC IS MISSING:
Windows Media Player cannot play the file (or cannot play either the audio or video portion of the file) because the MPEG-2 audio decoder codec is not installed on your computer.
The missing codec might be available to download from the Internet. To search for the MPEG-2 audio decoder codec, go to the WMPlugins.com Web site.
