Sound but no video when watching live TV on http://xfinitytv.comcast.net/live/network/

Sound but no video when watching live TV on http://xfinitytv.comcast.net/live/network/

HELP!

 

I have perfect sound but NO video any time I am watching live TV on http://xfinitytv.comcast.net/live/network/

 

I am using Mac OS X El Capitan, and it was working perfectly fine....then wasn't.

 

This has been going on for weeks, and nobody on the Xfinity nor Comcast support team seems to be able to help.

I'm having the same issues 9.14.16 @ 1:12am!  This is frustrating!

I had the same issue with my Mac 10.10.5 Yosemite. When you get the black screen, right click and select Settings. Then uncheck: Enable Hardware Acceleration. 

 

That should do it.
