I have a m3u with some channels and I gave Kodi a try after reading about it everywhere. Honestly, I think it's a bit of a overkill for my use especially considering how heavy on the RAM the app seems to be. On my pc it runs perfectly but when trying it on my Sony X800D the app sometimes is very laggy especially when you start browsing hundreds of channels. Then I tried the app called "IPTV" and it's much better, just something stripped to the core for loading channels and the EPG seems to work fine. What apps do you use or do you suggest I should try?
If you have android tv, try cumulus tv. They'll load in the android channels apps. Try it out
