SYMPTOMS
When you play back content from a Microsoft Windows Media Player 10 server or from a Windows Media Player 9 Series server with Fast Cache enabled, a problem may occur. You may receive the following error message from the client:

0xC00D002F: Invalid or corrupt data was encountered.



CAUSE
If Windows Media Player receives a sample with a timestamp that increases more than five minutes when compared to the timestamp of the previous sample, you may receive the error message that is mentioned in the &quot;Symptoms&quot; section. Typically, audio streams and video streams send multiple samples per second. Therefore, a large increase in the time in the timestamp indicates some kind of error. However, with sparse streams, such as script streams, this is different. Typically, sparse streams do have a large increase in the time in the timestamp between samples.
