Re: Dolby Digital vs. DTS vs. DTS-ES

204.133.173.194

DD and DTS, as I'm sure you know, are both 5.1 channel sound. DTS-ES is 6.1 (the extra 1 being a rear center). My understanding is that to get true EX or ES sound you receiver/processor has to be THX approved. Sony, and maybe Yamaha(?), have gotten around this by doing "virtual ES" which means the DSP creates a virtual rear center. Now if ES will down mix to DTS 5.1 I don't know. If you would like, I can try it out tonight and see if it will play in 5.1 as opposed to 6.1. I wasn't amazingly impressed with the DTS mix when I watched Gladiator the first time as the dialog seemed some what muffled.

There is an 1999 interview at bettercables.com with David Del Grosso from DTS that talks about DTS and its advantages. How accurate it is, since David is/was the Marketing Director for DTS, is your call. I don't know if it talks about DTS-ES or not.
