It is like if the film is originally DS and the TV broadcast it in Stereo: it is automatically in DS since the DS is encoded in the two-stereo channels.

Since the EX is encoded in the two channels of surrounds, it will be available both in DD and DTS.

Whenever volume intensities in both Left Surround and Right Surround channels reach the same level, that sound event gets steered to the Center Surround channel. I had thought there was some special encoding for the process, but that is really all there is. Just as any DD-EX release can be played in DTS-ES (provided there are discs for the film) if there is an SDDS track, it will also properly play the derived center surround when the signal is fed through a Dolby SA-10, DTS-ES processor or even one of those Smart thingies.

It is best to only play movies in DD-EX or DTS-ES when those films are mixed specifically for the format. You can get some undesirable effects when applying DD-EX or DTS-ES to something not mixed for it.

For example, my father recently upgraded his home theater system with a new Denon 4802 receiver among other things. He called me up and said his sound system was not working right when he played the special edition DVD of "The Abyss." The surrounds were sounding out of only the center surround channel. I told him that is only a 4.1 channel audio track with mono surround summed across RS and LS channels. You get total collapse to center surround when activating the DD-EX mode.
 

I presume that you are speaking of Home Theater. I know that DTS ES discrete is on DVD only, not theatrical.

"Seven" Platinum Edition, "Gladiator," "Chicken Run," "The Haunting" DTS DVD separate version and "Rush Hour 2" are the only ones I can think of from memory. The title track from Don Henley's "End of the Innocence" DTS music CD is encoded in DTS-ES 6.1. Sheryl Crow's "Globe Sessions" DTS music CD has DTS-ES 6.1 on all tracks.

That's not very much software. But judging by all the new DTS-ES 6.1 Discrete equipped receivers I have seen recently introduced by Sony, Yamaha, Pioneer, Denon and others, I would say we'll finally start to see an increase in DVDs with DTS-ES 6.1 tracks.
 

Only "special venue" theaters get 6 (or more) discrete channels.

DTS-ES adds an extra channel that each audience member straps to their chin. It is awesome.

Seriously though, yes, DTS-ES is the exact same thing as Dolby Digital-EX (fake rear surround channel). Though DTS has a much cooler adapter than Dolby's SA-10. Dolby's unit is a giant rack space stealing hulk, and DTS's unit is a tiny little thing that switches in and out of ES automatically when hooked up to the timecode reader. It also has as much impact on the sound as Dolby EX---next to none. At least the DTS-ES unit is cheaper, so if you want to spend money and get next to nothing, DTS-ES is the way to go since you will spend less.
 

More, DTS-ES has separate equalization for 6.1 or 5.1 channel configuration. Dolby has just one equalization.

Es means "extended surround"; can anyone remember me what "EX" means?

Yet even more, DTS-ES has a digital EQ and the DOLBY-SA10 has an analog EQ. The SA10 doesn't have too many frequency bands to fiddle with on the EQ. I can't remember if DTS-ES is the same or if it has more bands to fiddle with.
