My thought is it is a problem with their projector at
the theater not reading the audio corretly because the DCP file for sure has all 5.1 and
they play back on a computer with audio.
That would be pretty weird, though I know a small club cinema whose staff a sometime
forgot to switch on their L/R amp and so played center only for a few months. As the
center carries the most important dialog, and usually 'some music' as well, nobody
noticed.
The issue is probably easy to diagnose per se, the question is, how easy is it for you to
go to the cinema and test? I would first use an official channel test DCP, e.g. from
Dolby, to be played ahead of your DCP, that should make sure the audio system is setup
properly. An 'official' test DCP could also convince staff that there is something
wrong...
We had it before though, that people created DCPs with all channels mixed into the center.
It can happen based on the specific track layout of your source file. There are ways to
check wether the channels are where they belong (e.g. by opening the audio mxf in an audio
editor).
Here is a ZIP File with 'official' Dolby 5.1 and 7.1 channel test DCPs (the 5.1
should be sufficient in your case). Make theatre staff play it before your DCP.
