I've read about the definitions of DTS and Dolby Digital surround media. I know that the compression for Dolby is 12:1 while DTS is 3:1 and that Dolby transfers data at ~380k and DTS at 1.44M. That is all well and good but my real question is, what am I hearing that makes the difference. If I play Gladiator or Master and Commander in Dolby Digital and then I play it again in DTS (I'm not talking about the different movie intros) what should I expect to hear in the way of differences between the two. My ear may not be as calibrated to the differences as some of the more refined HT buffs here so I thought I would pose this question to help all of those who are in the same proverbial boat as me.
