When I'm watching live TV using the channels app with HD home run prime with the cable card. When it displays the local commercials that are fed from the cable company, it will go to a black screen. I can hear the audio which is fine but when it goes back to normal content it doesn't fix itself. When I use the HD home run prime DVR app it shows the video. As expected.
