Can't DLNA play Blu-ray ISO 3D files

Currently, DLNA does not support the playback of Blu-ray ISO 3D files.   However, you can use alternative methods such as SMB/WebDAV/FTP to play these files.

Another option is to convert the Blu-ray ISO 3D files to MVC encoded 3D MKV format files using makeMKV, which can then be played via DLNA.
