Today I installed kernel 4.14 over armbian-config - Watching TV on clients works much better than before! I will keep watching... Thank you so far!

Jernej, I think that's it. I am using a technotrend tt-connect s2-4600 on usb. As described here: Some get artifacts when watching livetv... But I don't understand what I shoud do when using mainline-kernel >4.8! Did you mean this? Patching and recompiling kernel is a little bit too much for me...

Downgrading to legacy-kernel is not really an option - cause I need to compile media-drivers on my own (needed module in kernel since 4.2)! So I'm very interested in getting it to work with mainline-kernel!

I can confirm this behavior! With an old installation of bananian with tvheadend Linux bananapi 3.4.108-bananian #2 SMP PREEMPT Thu Aug 13 06:08:25 UTC 2015 armv7l GNU/Linux everything works like a charm on several clients. But with a new installation of armbian (latest updates installed) I can see the same "stuttering" on clients as mentioned above.
