I concur wholeheartedly. In movie theaters, DTS is the bomb. On DVDs, the difference, in my opinion, can only be discerned by the absolute most discriminating audiophiles while listening to a movie DVD on a system employing the absolute best hardware. In other words, DD is all but synonymous to DTS in DVD-land. It once was explained to me by a movie / audio buff as well - and from what I remember, it is exactly as Pariah explained it.

On DVD, however, things are different: * Dolby isn't as limited by storing the sound data on the film. Dolby on a DVD is at a higher bitrate than in theatres. * DTS, on the other hand, is limited by DVD, and has a lower bitrate than in theatres. Hence the difference between Dolby & DTS are smaller on DVD than in a theatre; it's not surprising you can't hear the difference. Space is also important on a DVD: Dolby is required. DTS is optional. both take up space. So do you want to put on a redundant sound track, or 'extra' bonus material? Or do you want to shoot for a single-layer disc and save some production costs?
