Try set up the stream directly on an IPTV app on your TV, instead of using Dispatcharr. If you have a device with Android TV (either built-in to the TV or a steaming box like the Nvidia Shield or Onn one), try Tivimate.
The IPTV apps on non-Android platforms aren’t as good. On your computer, you can try tuning in to a channel using VLC or a web UI (if your provider has one) and see if it works better.
The best IPTV providers are hidden from the public (no public website or social media presence), and you need to be invited by an existing user. Unfortunately the one I use closed signups a few years ago, otherwise I’d invite you.




The IPTV provider should provide the EPG, either as a URL or via “Xtreme Codes” (which is essentially just a base URL for an API that provides both the playlist and the EPG).
