Are these specific video files, or everything you try ?

I have seen issues with another AMLogic platform that I compile OpenELEC distributions for, the C1+
Issues with HDMI cables with ARC or Ethernet channels in them causing HDMI EDID Checksum errors which then lead to further Kodi playback problems.

But as the WeTek Core comes with its own HDMI cable this would rule that problem out.
Are you using the supplied WeTek HDMI cable ?

Hi Thnaks again. My plasma is 3 years old and hasnt got a lot of options to check but has 24p smooth film.
I dont use HDMI cable from my Core but that will be the first thing that I will do. I have been useing few different HDMI cabels but not the cores one. Hope that will help, but...

Hi again Changed the cable with original Core and nothing changed. If I use 24p mode the picture is even worse. So keep it on 50/60hz but still soap opera....
Havent got a clue now.
Thanks

If the RPi2 and Core are now producing exactly the same results, then its either your TV's, particular setup, or visually you are sensitive to the picture output from both these devices. I've never seen someone have so many troubles, especially on a very mature platform like the RPi2 where video playback normally runs very smoothly indeed.
The only other common thing could be the codecs used or source of the video you are trying to playback.
