Please state your statement, I will try and post it on those sites (translated).A Google search revealed several websites which promote the use of the XMLTV file in Kodi - IPTV Simple PVR.
But since I do not speak (or write) Polish I cannot ask them to configure their software properly.
Could one of our Polish OpenPLi users help out here?

I have no knowledge nor use Kodi plugin so I don't know how to phrase it right myself, but I am eager to help you.
