journalctl -af

Seems you ran this as normal user, hence the relevant messages are all missing:

[xxx@localhost ~]$ journalctl -af
Hint: You are currently not seeing messages from other users and the system.
Users in groups 'adm', 'systemd-journal', 'wheel' can see all messages.

Please try again by running it as root as mentioned.

You need to unplug and re-plug your DVB dongle after you run that command, otherwise the log does not show anything of value.

But from the kaffeine output you posted it seems like to be an issue with your video driver. You could try running drakx11 and selecting the proprietary nvidia driver.

[mirej]

I used the open source GFX driver and proprietary nvidia (460) similar effect.
EPG works and recognizes OSD stations correctly.
Video is missing. Every now and then a frozen picture and sound appear.
Same for kaffeine and VLC.
