I've just tried this IPTV thing today and have a trial with Instant IPTV from the recommended sticky. I have followed the guide for EPG and guide but it only seems to half populate it? I'm using Kodi on Win10. Can anyone help me get it fully populated. It also seems sorted upto so far then all the channels go out of order and are then sorted alphabetically.
I agree with Bayard0, it sounds like you've likely done whatever you can.
Unfortunately with Kodi, EPG is never guarenteed. You're lucky to even have it half working to be honest.
I'm not sure why that one post is even stickied though, I'd hardly call some of those providers recommended.
Your best bet is to just read through different subreddits and hop on some services that are being recommended, not only by the resellers but by people that have experienced the servers themselves.
As of right now, if you HAVE to have a proper working EPG out of the box, you will need to buy a proper IPTV device. There is lots of info on that floating around here, and I'm in the process of reviewing some over at /r/iptvgta
