DNLA Plugin not reporting on whats being played

So i have set up and configured 4 DNLA devices.
3 are Kodi runnung Isengard on Openelc Raspberry Pis. another is the LG tv

But the DNLA device is unable to report in on any of the media which is playing
It reports in ok when i play Live TV

but not when its media on the network

Any ideas?

Thanks
