RE: WMP10 plays DTS DVD but MCE silent - HELP!

Given no responses yet I wonder if readers assume that MCE plays no audio at
all. To clarify this issue: MCE audio works fine except that I cannot get it
to play DTS or Dolby Digital soundtracks RELIABLY.
For example, just now (before adding this comment) I inserted a DVD that
offers only a Dolby Digital soundtrack. I clicked Play DVD in MCE, the relay
in the receiver clicked, and its display now says Dolby Digital with all 5.1
speakers indicating "active" status. Surround sound success.
I then returned the DVD to its root menu, looked at the setup menu to
confirm there were no options other than a THX audio and video test, and
resumed playing the movie -- now no audio. Silence. I tried several
navigation iterations to no avail.
But I can always exit Media Center and play the same DVD with soundtrack
perfectly decoded using Windows Media Player 10. In WMP I can stop the movie,
use various menus, change soundtracks, etc. and I never lose audio.
Try that in Media Center and I can hear the receiver's relays clicking and
it returning to stereo mode on its display and silence from the speakers even
if I just fast forward while playing the DVD.
All of this says to me that Media Center has a problem with DTS and Dolby
Digital audio since both it and WMP are using the NVidia decoder. See?
Incidentally, I ejected the DVD, reinserted it, clicked Play DVD in Media
Center, and the receiver's relays clicked, Dolby Digital decoding appeared on
its display, etc.
Unpredictable.
On the other hand, if I play a DVD that offers the choice of playing a DTS
or Dolby Digital soundtrack in a Setup menu, Media Center will always NOT
send audio to the receiver. So at least that's predictable: no sound if you
purposely select DTS or Dobly Digital.
Creative Labs support suggested perhaps it's a digital rights thing. Anyone
have some knowledge about this?
