Digital Cable Set Top Box - Digital Audio out

OK - does no one else out there use this option? I find
that hard to believe. I have a digital cable tv set top
box hooked to the media center pc via svideo and
everything is up and running. DVD's sound great in
Digital 5.1. My problem, I don't get Dolby Digital Audio
through the Tuner under MCE. My digital cable box has
SPDIF out and my PC has SPDIF in - but MCE only uses the
input on the hauppauge card - and that has to be analog
right and left. How can you tell MCE ot use the SPDIF
input for the tv tuner - vs the Hauppauge 250 input? My
last resort would be to hook up the digital cable set top
box hooked to the projector and the digital audio straight
to my receiver and bypass MCE! I don't want to do this!!
MS MVP HELP!

 

MCE uses an analog tuner/capture card, which encodes the video to MPEG-2 and
the audio to MPEG-1, Layer 2. It does not support any types of digital
inputs (audio or video).

MCE is a really cool product - feature wise. But without support for HDTV
and Digital 5.1 sound, it's obvious that Microsoft didn't design it to be a
component in a home theater environment where audio/video quality is
important.
