One needs to be very careful with the use of illegal characters in xml files, file names and especially in kdms it seems the servers don't perform a legal character check check on ingest and if one of these has inadvertently been used it can cause havoc to the server, this happened in the field in some territories with the film gnomio and juliet. the "&" was used in the kdm in one instance it caused an entire plex to go dark because the tms fed it to all the servers and and it crashed the licensing module the only solution was to re-install the firmware on all the servers to clear the problem.

Interesting information.

So based on this, it sounds like if you're taking something to be projected on an unknown system, it's best to upscale 1920x1080 content yourself to something like 1998x1080 beforehand. Otherwise it might show up in the wrong aspect ratio, depending on how the projector is set up.

Also, it sounds like sticking to "safer" filenames is the way to go. I trust typical command line UNIX sorts of filenames are better than more human readable filenames here.

In general, if you want to make a DCP that works everywhere it is quite simply..

Interop 24fps  Scope or Flat J2K video compression with 5.1 audio.
If you keep to that constraint, any cinema should play the content.

This is basically the standard the studios use, but also have subtitles and multi CPL's and more audio tracks.  But the above is the general DCP constraints to use for working everywhere.

MPEG2 in a interop container..  thats history and not really tested anymore by many SMS makers.  I would keep away from it now.

SMPTE is simply not well supported yet and should be avoided if you plan to distribute to unknown locations.. 

SMPTE is great (and some time needed due to fps) but only use it if you KNOW the system you sending to are SMPTE compliant and software versions are up to date with its support.

And in general, only IMB based DCI setup can support 30 and above fps in SMPTE.  (Ie Qube/GDC external media block system cannot do 30 or above.  Doreme can do upt to 30, not sure about Dolby.  IMB based units should do all fps theoretically, thut many SMS makers are still testing this. its mostly beta for most.) This is the general rule, if you break it you are likely to not work in some locations.
