I use a Dell Wyse 5070 (Super phat low power consumption Intel hardware) connected to a Samsung F8090 TV 1920x1080@50hz and only problems (sync playback to display is for a pal user of course enabled).
PVR is tvheadend. With amlogic coreelec all super. With windows 10 + kodi 21.2 on the wyse also all super.
With libreelec "Normal" all runs perfect but after 4-8 minutes audio pitch starts fluctuating much and then video stutters and buffering all the time.
With libreelec "legacy" pvr mpeg2 runs jerky stuttering like 10 fps. h264 720p 50fps pvr looks ok but when u do smthg withe kodi interface, interface + video stuttering and jerky.
Dont know but im absolutely not amused about this bad result.
So, is there a hidden switch for clean, displaying 1 frame after the other, absolte smooth video playback in 2025 , like c64 and amiga were able to do in the 80s/90s?
