DTS sound is "better" due to higher sample rate. AC-3 is usualy sampled with
384 kps and DTS
comes with 768 kps and on some DVDs it is even higher. I have DVDs with AC-3
and DTS and 
DTS sounds better (but that is my private impression, could also be beciuse
of the higher recording level) 
All in all I would say that there is no real audible difference between AC-3
and DTS if you do not own 
high end equipment (speakers).
