LG OLED65CS6LA PVR Playback Issue

[robbie1407 5]

- I have a problem with playing back recordings on my LG OLED65CS6LA. It happens on most recordings.
it seems to be only this device that is affected. windows app seems okay. Using hd homerun tuner. emby server on synology nas.
When i go to playback a recording it will show a still screen of the recording for about 1 second then just go blank.
All you can do after this is press backup to return to previous screen.

- I have tried seeking forwards and backwards but emby does not respond. I have tried restarting emby server and synology nas. i have played back on windows app and LGOLED55BV7 and all recordings play back okay.

- I have not seen any error messages.

- I have attached server log

- I have attached 2 videos, one of the LG and one of the windows app to show playback issue on the LG

 

many thanks

Emby menu visible but streaming fails - LG OLED.

Apparently this may be resolved with LG setup options.  Often different brands and models require permissions and settings.  Viewing an Emby page on a TV app does not mean that all streaming should be working. Video streaming may be blocked by a TV setting, as well.

In latest log Error in GetSpecificMappingAsync occurs 119 times.

Linux access rights?

Emby issue?

@visproductionthat's the upnp plugin telling emby it can't configure the router.

And that's not what this is about.

i did switch locations and reverted back. although the recordings still act the same, i have set up some stuff to record to see if it acts the same. will report back.
