Looks like I need to wait for DVB issue since LE switched to kernel 4.9.x to be fixed first. Than I will buy this killer card DD MAX S8. Not sure when LE 9 will be released. So it helps me nothing to switch to 4.14+ now, if I still see artefacts what makes TV useless. Once this is done I'm willingly to sponsor this driver inclusion for LE 8.2. Until then I'm stuck at 7.90.010.
