DLNA does not index some large files

Hello, all.

Recently bought WDLD 6Tb, I met issue with DLNA server. Server does not index some large files (more than 4Gb) but some files are indexed.

I still may see these file using common file manager and therefore watch movie. Does someone have an idea what is wrong or it just a bug of the DLNA server?

I’ve installed the latest firmware, tried to rescan and rebuild DLNA database, rebooted WDLD, but with no any success.

What is the extension of the files that are not being indexed? You can follow the link below to view the supported file extensions.
