For DirecTV TV services which include DVRs and receivers, Using Apple Lightening TV adapter with Mobile DVR I am very excited with the new DIRECTV mobile app. It works great. With one exception....I watched a couple of shows that I downloaded onto my iPhone on our Camper's flatscreen. I was even able to stream. But then it started acting up. I could get audio but not video. Waited a bit, tried again, and it started working fine. Inspected my adapter and HDMI cable. All seem fine. Tried other apps, they were all fine as well. Any suggestions ?
