Hello,
I have recently replaced my RPI2, which used to run OpenElec (Isengard) with RPI3 with LibreElec (Jarvis). I am using Simple IPTV addon with a set of IPTV channels from my provider.
The problem is that the same exact channels work perfectly on my my OpenElec installation, while on my new setup it is constantly buffering, making the watching almost impossible.
Neither of the RPIs have any advancedsettings configured. I have also tried swapping SD cards between RPIs, to rule out it being a hardware/network issues. Anyhow, my old OpenElec installation works fine on RPI3, while my LibreElec installation keeps buffering despite it being RPI2 or RPI3.
Any ideas? I am pretty desperate, as none of the solutions I found so far helped me.
