Hardware-Created ASF Files Stop Playing in Media Player 9 Series. When you try to play back certain ASF files created by hardware devices, you may receive the following error message approximately three or four minutes after playback has started: 0xC00D1199 -- Windows Media Player cannot play the file. The file is either corrupt or the Player does not support the format you are trying to play. You may also receive this error message when you seek past the three- or four-minute mark by using the track bar. When applications built on the Windows Media Format play back files, the applications make certain checks to determine if a packet is valid. The Windows Media Format incorrectly handles a case where the time wraps around because of the maximum value possible for numeric data types. The patch updates Wmvcore.dll from the original WMP9 version 9.0.0.2980 to 9.0.0.3001. Direct download Source: Microsoft
