DTS stands for "Digital Theater Systems", where did you see "Dolby" in this 
name? In many cases (I could say in most) DTS stream _is_ better than DD 
(Dolby Digital, here comes the "Dolby") or at least different! Of course, you 
must own something better than Radio Shack multimedia speakers to figure that 
out. And finally, about the picture quality, thats plain FUD! Have you ever 
heard of Superbit DVDs? For the vast majority of the movies, a dual layer DVD 
is capable of Superbit-quality picture, and at least two audio streams (DD 
_and_ DTS).

To Vladimir Mosgalin:

They don't make 640k AC-3 for the same reason most people don't even think to 
create 512kbps mp3s: AC-3 and mp3 are lossy codecs/algorithms, designed for a 
very specific range of bitrates. So, an 640k AC-3 is just Bad Idea(TM).
