Dolby Digital, DD EX, DTS ES, THX, etc.


Okay, I apologize but I am getting lost here.
Could anyone please explain to me what are the latest developments regarding serious 8 channel sound formats? What are the official names of the standards?
What is DD EX? Is it DTS ES compatible? How does THX relate to EX? Are EX and ES standards to be taken seriously in private theaters?

Hope to learn from this guys ... thanks!

An important footnote: Only THX licensees are allowed to use the term "EX" on their gear. Just one more point of confusion for the buying public. I, for one, get a kick out of how carefreely the manufacturers will will throw multiple formats/choices/upgrades/labels at the public, expecting them to comprehend it all, and seemingly oblivious to the mass confusion and resentment it initiates (especially from those who were convinced to spend large chunks of $$$ on the "state of the art" surround sound). It often appears that the state of the surround sound world closely resembles the weather in New England..."If you don't like the forecast, wait a minute".
