THX is just a guarentee of certain qualities, it's not a sound format or
encoding. THX is more like a seal of approval than anything else, and one
of dubious worth, FWIW. For example, a DVD with the THX logo might still
be a non-anamorphic transfer, but everyone would agree that a (widescreen)
DVD should be anamorphic if it's meant to be of the highest quality.

If you mean Dolby Digital, this isn't entirely true. Dolby Pro-Logic is
what you're describing. That has left, right and rear channels
only, AFAIK. Dolby Digital is a different format to Pro-Logic. Both Dolby
Digital and, like DTS, features fully discrete 5.1 channel sound: left,
right, centre, rear-left, rear-right, and low frequency effects (the .1),
which is sometimes called the subwoofer channel, but that is slightly
incorrect. (Although the way the LFE channel is usually used, it might as
well be true.)
I think DTS stands for Digital Theatre Sound, but I often get the name
wrong so don't quote me on that, heh! (In case anyone thought the D in DTS
meant Dolby.)
There are also new versions of both DD and DTS, I think called DD-ES and
DTS-ES (Extended Surround). (Actially, I can't find the article I read on
DD-ES so I could be remembering things wrong! DTS-ES definitely exists,
though.) The ES part gives DTS yet another channel for rear-centre.
All very exciting, I know... heh :-)
