Which version of mono? Sounds like the bug in 3.4.

To fix the database the media info for the affected files will have to be cleared out (though doing it all won’t hurt as it will be rebuilt on the next series refresh and disk scan).

Yep, 3.4, seems I am at the mercy of my NAS manufacturer to update it for me

sorry for the bother.

Unless you can compile from source, unfortunately yes. Is it a synology? If so: https://github.com/SynoCommunity/spksrc/issues/671#issuecomment-53181568
