SYMPTOMS
Assume a scenario where you play a DVD movie in Microsoft Windows XP Media Center Edition 2005. The movie has a Dolby Digital 5.1 Surround Sound soundtrack or a Digital Theater Systems (DTS) soundtrack. In this scenario, the audio signal may drop out for a moment every few seconds.



CAUSE
This problem occurs when the audio card and the MPEG-2 decoder that is used by Media Center Edition 2005 both have Dolby Digital (AC-3) audio decoding enabled. This may cause a conflict between the audio card and the decoder when you play Dolby Digital 5.1 Surround Sound audio or DTS audio.



RESOLUTION
To resolve this issue, disable your audio card's AC-3 decoding functionality. For more information about doing this, see your audio card documentation or the manufacturer's Web site.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
