What software decoders support Dolby Digital audio?
All software decoders will down-mix a Dolby Digital 5.1 track to a 2 channel PCM audio track. Newer versions of Win DVD and Power DVD will also pass a Dolby Digital signal through the digital output that is available on some of the newer sound cards (like the Sound Blaster Live!) to an audio receiver equipped with a Dolby Digital audio decoder. Some of the Cinemaster based players (including the ATI DVD player) will also allow you to pass the audio stream through a sound card’s’s digital out. However, to do this you will probably need DVD Genie.
