playback issue 8008 - XFinity

I am using the Xfinity Stream TV app to watch TV on my iPhone 6. I plays TV and movies fine on the small screen. But when I try to connect it to a big flat screen, it stops and displays "Playback Issue :: 8008". It further states Screen recording is not permitted while watching video. Please disable screen recording and try again.
I wasn't using screen recording,but added it to my control panel, so I can make sure it isn't turned on. But I still am blocked, as soon as I connect a lightning cable to my phone. This cable is in turn connected to an USB powered HDMI adapter, which connects to the flat screen.
Anyone know how to get around this block?
