Shameless bump
i have kodi on my PC & just put it on a firestick for a mate..
sportsdevil, covenant, elysium, ares..
but for sport it's always a pain .. no stream etc.. i've done the usual tweaks in settings but still usually zero !
So any pointer's or help be sound....
Rising Tides is usually spot on & MaverickTV (sports,tv,movies) and I have been using Poseidon recently for movies/tv,it is an Exodus fork that uses the nan scrapers,plenty of 1080p and loads of 720s in the results.
Have you checked that your modem firewall/child filters are off (the isps all call their version differently) ?
And you should tell your mate to put these live tv apps onto his stick UKTVnow,Livenettv & swift streamz are all pretty good for the footy & Mobdro is ok but they block during the football (works with vpn).
