They exist. Any receiver that has DTS ES will also feature THX EX (the official home name for EX). You can play the disc back in EX using the Dolby Digital tracks and it will decode just fine. Maybe the DTS ES tracks are DISCRETE, an advantage that Dolby Digital cannot offer at this point.

Part of the confusion regarding "Gladiator" is in the rules Dolby Laboratories has set for the use of the Dolby Digital Surround EX logo. That specialized logo is only for film presentations. On DVD, only the Dolby Digital logo can be used, with any Surround EX notation printed in text. Here's a link to an Adobe Acrobat PDF file on Dolby's website describing the rules: http://www.dolby.com/trademark/co.in.1200.MarkSurEX.pdf
You'll find the stuff regarding DVD on page 2 in sections 3.1 and 3.2.

My own personal opinion is that Dolby's rule is just plain counterproductive and only hurts them on being able to promote DD-EX. I think if a movie has been mixed for EX, the DD-EX logo itself should be used on everything, be it the film release or on the DVD. If a home theater receiver can do DD-EX, that logo should be on the front panel. Oh well, I got a BFA degree from a high powered art school, but what the hell do I know?

DTS apparently has the opposite rules for film and DVD. To this date, I have never seen a DTS-ES Extended Surround logo placed on a film poster or the end credits of a movie. The only place where I have seen it is on the packaging of DTS-ES 6.1 Discrete DVDs and Music only CDs (such as that nice sounding Sheryl Crow CD).

Home theater hardware, such as receivers and surround controllers must offer all DTS-ES modes, including the full discrete 6.1 format, to be able to carry the DTS-ES Extended Surround logo on the front panel of the machine. If it only does the matrixed variety, then only the regular DTS Digital Surround logo can be used.

That DTS-ES logo rule is a handy thing to remember if you are in the market to buy a true 6.1 receiver and don't wish to get hoodwinked by some stupid sales droid trying to offload some other kind of receiver on you claiming that it is 6.1 when it really isn't.
