For some years, everything with my Kodi/LibreELEC installation was just fine, but recently (I think it started with the 10.0.2 update) some weird things started to happen. Basically when I start playing some movie on my TV (connected to RPI4B 2GRAM, LibreELEC 10.0.3), it plays well for some time (30min-1h, sometimes ever more), and then kodi interface pops up and the movie is repeatedly and constantly being paused and resumed again. It happens 3-5 times per second, every second till RPI is rebooted. When rebooted, everything backs to normal, but after some time, it stars all over again.
In the Kodi log, I can see the following when the pause-resume event starts to happen:

What could be wrong with my Kodi/LibreELEC installation? Does the problem lie in RPI, my old TV (15+ years), or the software is to blame?
