Play DTS Wav files under Winamp?

I have just a generic WinTel box, no fancy sound card, etc. I would like to play DTS (Digital Theater whatever) .Wav files using something like Winamp. I only want standard stereo ouput, no 6 six channel output is needed.

Is this doable? Is there a plug-in? I’ve Googled around and people talk about enabling SPDIF connectors and all, but I just want a simple software solution. They’re just bits after all.

(I am dreading that the “Proprietary” word is involved.)
