Hi All,
I always use DTS when available. It was my understanding that the DTS signal uses a different compression algorithm and is nowhere near as compressed as DD. So, as a result, DTS sound is more dynamic, as it contains more information.
A good example of this is the movie Pitch Black with Vin Diesel. If you watch the scene when the space ship crashes in DD, and then DTS, you will notice a definate difference ie: The DTS track has more spatial information and more seems to be happening on the audio level regardless of volume.
This is a direct quote from a DTS Wiki (link below)
One advantage of DTS (for DVDs) is that it has a much higher bitrate than equivalent Dolby tracks. DTS 5.1 typically uses 768-1536 kbit/s (overall), while Dolby 5.1 uses 384-448 kbit/s. Proponents claim these extra bits give higher fidelity and a greater dynamic range, providing richer and more life-like sound. They also claim that DTS is louder and has less hiss at the same volume.

Of course I could be wrong.
