When you playh content from a Media Player 10, or Media Player 9, 'server', with Fast Cache enabled, the client receives:
0xC00D002F: Invalid or corrupt data was encountered.
This behavior will occur if Media Player detects that the previous sample is more than five minutes old, compared to a current sample. While this typically indicates an error, a sparse script stream may have a large increase in the timestamp between samples.
