If you use Kodi and don't mind paying a nominal monthly fee than check out on-tapp . They have a FB page if you have questions.
Integrate where? On what device? Explain.
I have a IPTV add on for kodi and im thinking about getting rid of my sky subscription and adding a sat tuner card to my htpc and I’m wondering if I can add them both to a TV guide
m3u-builder can handle multiple sources simultaneously including tvheadend.
