This article was previously published under Q284852 SYMPTOMS
When you are using a proxy server that requires authentication, if you try to play content that requires a newer codec than you have, you may see a black screen where the video content should be.CAUSE
Windows Media Player cannot directly download codecs through proxy servers that require authentication. The player must authenticate against the proxy server before it downloads the codec.WORKAROUND
Before you view the content that requires a codec upgrade, open Windows Media Player, and then open the Event Guide. Your proxy server should prompt you for authentication. After you see the Media Guide content, try to play the audio or video content that requires a newer codec. Because the proxy server has already authenticated Windows Media Player, you can update your codec.STATUSMicrosoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
