Here's my setup. 30Mbps download, Firestick running tivimate.
I'm using Apollo Group and have had no issues. I can watch anything with absolutely zero buffering...except sports. Espn buffers every 10 seconds no matter what's on.
Here's the ironic part. I watched my teams preseason football games and never once buffered. I tried watching a few this past week and it buffers every two minutes or so. Same goes with MLB, NCAA games. Also, if a game is on CBS, NBC etc, it will buffer for the game, but if I watch Wheel of Fortune, Jeopardy or just any game show, or tv show, it won't buffer at all.
Anyone else experience this?
