The technologies are both comparable, both have their pros and cons, its just that stuff mastered in DTS tends to have a better original mix. Myself, i prefer DTS. I have yet to find a dvd where i would listen to the dd mix over the dts.

If you have setup to output through a digital out, it bypasses the dac and outputs the raw ac3/dts to your receiver/amp which does the decoding, not your audigy.
