I have run into this problem a few times. I will be watching an Episode of a TV series and it will keep buffering every minute or lass. For instance Agents of Shield 1x7 the hub. The interesting thing is I have tried changing sources, changing addons ( 1 Channel and Genesis) Changing devices Windows PC and Android tablet, and even the WiFi source (but only with the Tablet), and I keep having the same problem. Is it a problem with the original source, and are there any fixes? Turns out I only have this issue with 1 Chanel.
