Are the DCPs Interop or SMPTE? I don't know if this issue applies to your server and/or projector, but we have an ongoing issue with the setup in one of our houses whereby the fact that we have a series 1 projector forces us to use an older version of the server software (NEC NC2500S and Dolby DSS200/cat862 running 4.3.5.13), and this will sometimes fail to display subtitles in SMPTE-format DCPs. Interop subtitles work reliably. I haven't had time to read up on precisely why this is, but have heard that it's something to do with the amount of memory needed by the projector to render the subtitles, and that the SMPTE way of doing it uses too much for a series 1.
We show foreign movies all the time and so this is a known issue for us. On the technical info sheet we give to festival organizers and suchlike we ask them to provide Interop DCPs of subtitled movies if possible, and if not or if it's out of their control, to bring a BD backup as well. Those BDs have saved our bacon several times. But for somewhere that mainly shows mainstream, first or second-run Hollywood and gets a subtitled show once in a blue moon, I can see this issue causing a gotcha.
Though as Carsten points out, receiving a hard drive with multiple versions of the DCP and a key for the wrong one is also a known hazard. I've had that happen for a festival show this weekend, in fact. Another key hazard is when a DCP arrives from Europe with a key written for their time zone (8 to 10 hours ahead of here), not ours, to close at the end of the playdate.
