This may be the same as another user is seeing:

Sony SRX 320 Projectors with LMT 3000
Anything from 2.14.x seems to work (SMPTE + Interop), anything from 2.15.x does not.

Tested DCPs made by me with 2.15.16, 2.15.183 (bad) and 2.14.56 (good)

Tried removing markers (f33243f9a0d2958c0e10461d1cc5e5a3eb1c216f in sony branch) but some different error occurred - possibly something funny about that DCP.

Tried importing the 2.15.183 DCP into a project in 2.14.57, sent as made214assets215. That works.

a22f917a520ec450055b7033ecded84dae190a9b works - no markers, <ContentVersion> labels and <AnnotationText> in reels filled in.

b7bb04a585562d895898984fc086e3de8f93f105 does not work - no markers.

521f7a364a0c797eeac224a5f01eaeff8b6365c7 works - includes markers and has <ContentVersion> labels and <AnnotationText>

Would appear that this fixes it:

Also removing the tags works.

Removed empty AnnotationText tags via a libdcp bump in df34292525addcd497aed990fd606186b6ff5dbd

Should add this to the verifier.

Fix is hopefully in 2.15.186.

Just need acknowledgement from the new reporter and Jim to check.

Confirmed fixed by the new reporter.

This is all unencrypted SMPTE, right?

Unencrypted SMPTE and Interop, I believe.

Unhooking from 2.16.1 as no feedback is yet forthcoming.

Assuming resolved.
