When I try to play DVDs on a Dell Vostro 1700 laptop (XPPro) with WMP
11.0.5721.5145, the 2 channel audio presented at the built-in SigmaTel stereo
out socket sounds like it's just the music/FXs channels. Dialog is way down
and mostly unintelligable behind ultra-wide stereo music and FX.

Oddly, dialog that should be off-center is not as loud as I would expect if
the problem was the center channel either missing or somehow out-of-phase
with the dialog component common to the front left-right channels.

The tech support info from the Help/About menu lists the following audio
codecs:

But how do I know what WMP is using for DVD audio? And if I did know, how
might I correct the problem?
