Many thanks for the update - it’s nice to see things progressing 
Rather than the constant buffering when I select a live TV channel from the guide, I now see one of the following scenarios:
- The programme buffers and plays
- The programme buffers and then displays “Live TV playback could not be started”
- No buffering, no feedback in the UI - nothing when I select the channel
- Squashed resolution
I’m UK based with Freeview (DVB-T2) from a HDHomerun Quatro. Nothing was recording at the time so all 4 tuners were available.
The Plex PC is a Dell R7910 Precision Workstation with 2 x E5-2650v3 (10 cores each) CPUs and 128GB RAM so not particularly busy.
Issues 1 and 2 were both intermittent often on the same programme/channel - retrying when the error was seen would see it resolve 9 times out of 10. Equally stopping playing and starting the same programme could see it fail. Example Channels: BBC1, ITV1, Channel 4, Five.
Issue 3 would always happen on the same channels no matter what. For example: Paramount, Sony Movies, Sony Movies Action, 5 +, Dave Ja Vu and Horror Channel.
Issue 4 only happened on TBN UK - Viewing the programme appeared more squashed than 4 x 3, almost half of 16 x 9 (8.5 x 9) - using Plex for Windows on Windows 10 displayed in 16 x 9.
I’ve not gone through all TV and radio channels - just a selection if the TV stations to see what the Live TV and DVR functionality is like.
