There seems to be an issue with encrypted SMPTE DCPs on Sony SRX-R510/515 (XCT-S10 Server)
machines.
While unencrypted and encrypted INTEROP DCPs work, as well as unencrypted SMPTE DCPs,
encrypted SMPTE DCPs do not work. They seem to ingest fine, and the KDM is properly
attached to the content, but when trying to play, it gives an error: 'CPL xxx is not
playable. Time period of the CPL or KDM is not present.'
KDM type is Modified Transitional 1.
This may be a Sony specific issue, but maybe someone has an idea what is going on. Seems
that a signature method for the CPL or MXF is not supported or handled properly?

While with proper CPL/KDM, this should be (this example is provided by Sony, but it seems
this is unencrypted, so, no proof):
