Just a few additional comments, in general there is no difference in single or dual disc feature. Single discs are created simply because the feature data is small enough to fit on one disc. The player does not care if one disc or two are loaded as long as they are the same feature. DTS does not use DVD’s because many older players have CD-ROM drives. With two disc features its true, reels do not always go in numerical order, such as “A disc reels 1 – 4”, “B disc reels 5 – 7”. The reason for this is disc space is limited and not all reels are the same length, so sometimes reels are mixed to fit on a disc, again doesn’t matter the location of data (drive or disc) since the player searches for what it needs. In addition to the feature audio the disc contains an .exe file which loads each time the DTS-6 or 6D is powered up and the disc is booted. It was normal practice to power-cycle these players every time a different disc was loaded to ensure the correct .exe was loaded, all discs made today have the same .exe file although it’s still recommended to power cycle the player when changing discs.
There are many possibilities why a disc won’t play; being just a single disc is not one of them however the disc itself could be suspect. Some of the things I would ask are, when you put the single disc in the unit does the “SYSTEM” LED blink?
All DTS systems will indicate if they are ready to play, the 6 and 6D have the LED, the 6AD has the disc icon which darkens, the latest players will actually state “READY” on their screen. If a "SYSTEM" LED is not blinking with a 6 or 6D, I would recommend trying different drive and power cycling the player. If doing this corrects the problem you may have a bad drive. If moving this disc to all drives does not work perhaps you have a bad disc. Where did the disc come from? Is this a copy or a pressed disc from DTS? If the READY LED does blink, are you getting timecode? Does the disc title match the print title?

I haven't seen this issue in person, and now confirming that there is no known reason why a player would act like that, I'll make sure to follow all proper diagnosis next time the issue arises (next time there is a movie with the audio in a single disc).
The discs involved would've been, nonetheless, the original ones shipped with the movie. Hopefully the projectionist checked the title and status lights to confirm the barcode was reading and the disc title matches the film. I haven't been told how the status lights behaved, just that they can't get the DTS to play whenever the film comes with just one disc, only when it comes in two or more discs.
Most movies arrive SRD here, so it may be a while, but we'll figure out what's going on eventually.
