What software decoders support DTS audio?
The newer versions of Power DVD and Win DVD can both pass a DTS signal through the digital output that exists on some of the newer sound cards (like the Sound Blaster Live!) to an audio receiver equipped with a DTS audio decoder. There is also a version of Win DVD that will do full decoding of a DTS audio stream. This means that you will not need a DTS decoder to listen to the DTS audio existing on many DVDs. If you have a 6 channel sound card (like the Sound Blaster Live! 5.1), the DTS version of Win DVD will allow you to enjoy the full benefits of 5.1 channel DTS audio. If DTS is not supported by a software decoder (or by the certain settings in Win DVD or Power DVD), the audio stream will be ignored by the software.
