I am currently experiencing 3 issues and for the sake of not mixing things I have kept them separate.
Issue 1: What reported in this thread [ SAD Face / Crash while playing 4K movies]
Issue 2: What reported in below thread and SAD Face while Skipping with progress bar
Issue 3: Each morning can’t play any movies and require to reboot the VERO device [This is the issue I PM you but now I have created a topic for public tracking]
I will post new logs regardless. I am using Synology NAS and nothing changed in the NAS side since KODI 17. I also post the NAS speed test results and we can’t blame the NAS.
Also I got no issues playing same 4K titles via my MAC KODI on WIFI and this also showing no issues at NAS side.
If you truly believe it’s NAS please share some tips and help to chase the NAS manufacturer.
