Whenever I try to watch live TV through the Emby Theater app I get a spinning circle for a few minutes before the app freezes.
The app is from the Emby site, not the Windows store.
Live TV will playback on my phone and through the web player on any device.
It will not play through androiid TV on an Nvidia Shield.
I use an HDhomerun tuner.
The tuner will play using NextPVR, and the HDhomerun app.
E,by theatre will still not play LiveTV if using the NPVR plugin in Emby server, however I can still use the web player or my phone.
In the Emby server log file it shows the stream being accessed then writing to a transcoding file. At the point where the stream is to be played by Emby Theater it seems to try and access the local loopback address rather than the address of the server or tuner.
Beyond this problem, opening a TV stream through Emby is hugely slow compared to NextPVR. NPVR takes a second or 2 while emby always takes 10 seconds or more.
I have attached the part of the server log from just before trying to watch LiveTV.
