this is my 2 cents of freezing, some say, its on our end, the end user, router, box, ISP, etc, just for snicks today, i cleaned cache on my M8, deleted a bunch of useless addons, etc, running kodi 16.1. tried different skins, so after all that still bufferes when I watch fox news, so i switched to an addon on that has fox news, and it runs perfectly and has all weekend, buffering may be on some end users but not this one, I did reenlist for another year also, they`ll get it fixed sooner or later
Update, so I decide to try my vpn, lol no buffering on any channels
