Audio does not play correctly when you use a video playback application other than Windows Media Center to open a .wtv file on a Windows Vista-based computer that has Windows Media Center TV Pack installed

On a Windows Vista-based computer, you have Windows Media Center TV Pack for Windows Vista installed. When you use a video playback application other than Windows Media Center to open a Windows Media Center TV recording (.wtv) file that contains more than one recorded audio track, the audio may not be played. Or, the wrong audio track may be played by the application.
This problem may also occur if you burn the .wtv recording file as video to a CD or to a DVD and then try to play the video disc.
This problem occurs because some software cannot handle multiple audio tracks in a single .wtv recording. In this case, the program may be running in a compatibility mode that enables Windows to select the default audio stream to use.
However, if a particular recording contains audio streams of different subtypes, such as both MPEG and Dolby Digital audio streams, Windows may not present the correct audio stream to the application.
