Hello,
the IPTV-service I use gives me around 30000 channels. This is making restarting Kodi a not fun thing to do. I subscribed to xtream-editor to disable a lot of the channels. Now I have maybe around 1500 channels left, but Kodi is still taking forever to load.
I imported the M3U-link xtream-editor gave me. It has been loading for 10 minutes now.
What am I doing wrong?
What you are doing wrong is using KODI for IPTV.
PVR simple IPTV client is unstable and not recommended, probably hasn't been updated in years but i'm not sure about that.
On a shield, TiVimate is the best, by far.
