Samsung F series (2014) renderer

[JCGJCGJCG]

Hi, I was trying to search on the forum but I don't get any results: I am trying to get my head around renderers and config files, but it is all a bit confusing. Isn't there anybody who has made config files that one could download? If I saw the correct file for my TV, I would have a better chance understanding them and creating them. My TVs (Samsung UE55F8090, some older Sony Bravia's and a Sharp Aquos) sometimes play files, sometimes don't, sometimes show subs, sometimes not...
Any help is greatly appreciated...
