Many newer movies are recording using DTS from what i've seen. Can't remember the specifics but i know that DTS uses less compression allowing greater dynamic range. Sonically, it is superior to either THX or AC-3 aka "Dolby Digital". I won't say that DTS offers the same improvement over DD that DD did over THX, but it is there and noticeable if you want it. This is besides the fact that decoding a soundtrack using the same format that it was encoded in will allow you to experience the performance as the director's and sound engineers intended. Sean
