DD Out in Windows MCE 2005

[Woodchuck2000]

Hi All,
I'm in the process of (re)building an MCE machine at the moment. I'm trying to get Dolby Digital passed through the onboard optical S/PDIF output - what's the easiest way to achieve this in terms of software setup?

Also, I've downloaded a couple of TV episodes recorded off HDTV with their original DD soundtracks - how can I get MCE to play these with DD passed to the optical output?

Any help greatly appreciated!

Unless I'm wrong - I think the latest nvidia Codecs handle SPDIF out?

I think this is one for Wildmonkey?

What audio feature do I get with the NVIDIA PureVideo Decoder?
The NVIDIA PureVideo Decoder supports Dolby Digital 5.1 decoding downmixed into 2-channel stereo, Dolby Pro Logic surround sound, Dolby Digital 5.1, and DTS S/PDIF digital output. If you plug in stereo speakers or headphones into your computer you will hear all of the audio in stereo mode out of two speakers. In order to use surround sound 5.1 speakers you will need to use an external audio decoder and change the NVIDIA PureVideo Decoder audio properties to S/PDIF mode.

How do I turn on S/PDIF mode?
Browse to the NVIDIA PureVideo Decoder Properties and select the “Audio” properties page. Click on the “Speaker Setup” button and select “a receiver” and then check “via an S/PDIF cable”. After this is done, the NVIDIA PureVideo Decoder will be in bypass mode and output all audio to an external receiver or decoder, including Dolby Digital 5.1 and DTS surround sound.

Does this product support Dolby Digital 5.1 surround sound for my 5.1 speaker configuration?

Does this product support DTS surround sound, my 5.1 speaker configuration?
