If you have a sound card with Dolby Digital Live encoding that would output all PC sounds in Dolby Digital.
Just tried it with my X-Fi titanium. (I usually use whatever the disc has (DTS orDolby) via SPDIF option in PDVD.
I started playing a DTS encoded disc, selected system audio in PDVD and set the card to Dolby Digital Live encoding. My amp picked up the audio from SPDIF cable as Dolby.
Hope that helps if you're willing to get a sound card.
