Windows Media Player error C00D10D1: XVID MPEG-4 (XVID)
Missing codec: XVID MPEG-4 (XVID).
Windows Media Player can't play the file (or can't play either the audio or video portion of the file) because the required codec isn't installed on your computer.
For more information about the XVID codec, visit the XVID website.

Use caution when installing codecs that you find on the Internet, particularly some of the free codec packs that claim to include codecs from a wide variety of companies or organizations. Incompatibilities are known to exist with some of the components in these codec packs that can cause serious playback issues in the Player and other players, lead to system corruption, and make it difficult for Microsoft Support to diagnose and troubleshoot playback issues. For these reasons, we strongly discourage you from installing these codec packs, and recommend that you remove them if you have installed them and you are having problems with the Player. Install only codecs, filters, or plug-ins from trusted, authorized sources, such as the website of the official supplier. Even then, use caution: some codec suppliers offer minimal customer support. Before installing any digital media components, set a system restore point. The restore point enables you to return to your original system configuration, if necessary.
