A few days ago I added DVR service to my account and got a new box at the local store. Ever since then none of the live stream ESPN3 channels work anymore. When I select a stream it goes to the screen with the 3 dots then just goes black and goes back to whatever last channel I was on. Xfinity Stream on a laptop or computer works just fine. I can see all the ESPN3 streams on there.
Called tech support numerous times and was escalated numerous times. They can't seems to figure it out. Can one of the Comcast folks here give me a hand?
