Jellyfin is a terrible M3U player, use a dedicated app for IPTV.

did you just drop the full index into the config, like the 'how to use' image shows in the repo's 'readme'? take that out, it's all 10,000+ 'channels'. go into the repo's 'streams' directory and find one or a few for your country and add those instead (load the 'raw' url for each in the browser, then copy the resulting address from your browser address bar into the config).

I watch iptv with Kodi and it's pretty solid.

But I went through the same thing with iptv-org. It seems many of the listed channels are largely dead. I manually scrubbed the english list by checking the channels but it was pretty brutal. I think like 200-400 channels were working out of 2000+.

There are also online m3u checkers if you search like "m3u checker". I've used some web-based apps. They're somewhat slow but ok. There's also an m3u checker that you can install locally. I haven't tried it yet but I'm wondering if it might be faster.

I try not to bother with obviously pirated channels because they usually go down pretty quick. I'm much more interested in legit channels that will stay up.

Lastly I also have all the Pluto channels with EPG. I used this app for the channels and EPG.

I also wrote some scripts to download/merge channels and EPGs. TBH it's kind of a PITA but it's like a hobby.

(edit: One last thing... I noticed that some channels worked with VLC but not Kodi. I had to adjust some settings in Kodi to make them work. In particular I had to change my user agent to OKHTTP for Pluto channels.)

IPTV. I use Trivimate on my Android box.

@plankton I've added the same to mine and it works for me.
