DTS files play at 2x speed

[MrGneissGuy]

WinampAC3 will play my DTS files, but it plays them at 2x the normal speed.  It reads the sound length as half of what it really is (reads 5 min song as 2.5 min).  Is this a configuration error, or is something just dead wrong here?

I downloaded a test DTS file from http://www.sr.se/cgi-bin/mall/index.asp?programid=2445 , and it played properly.  I thought I might have ripped my CD improperly, but they play flawlessly in VLC media player.
