Tvheadend

Does anyone have a repository listing of IPTV providers that work well with TVHeadEnd?

Been wanting a trial to try with TvHeadEnd and eventually pay for subscription.

Newbie here with new working TVHeadEnd server running well.

Server works well with standard HD over-the-air Antenna but most are non-english channels.

Been looking for a good IPTV service provider, but most require some apk, tokens, or wierd software package to install. No thanks.

There's a lot of providers I found, but not many provide free trials and web sites look really fishy.
