When you use Windows Media Player version 6.4 to play a .wav file, you may may receive an access violation error message.
This problem can occur when the Quartz.dll file (a Microsoft DirectX version 3.0 component) reads 4 bytes beyond the last piece of information while parsing the .wav file properties for author information. When this occurs, an access violation error message is generated because Media Player 6.4 uses the DirectX 3.0 version of the Quartz.dll file to process .wav files.
