My HR24-100 has started making loud noises so I ordered a new (reburbished) one. Received an HR24-500 and activated it yesterday. I put in it the same place in my bedroom, same HDMI already connected to the TV, etc. Picture, but no sound and no Whole Home. Additionaly, I had a longer HDMI that I would plug into my previous HR24 when I wanted to watch TV in the room across the hall. So I plugged in that HDMI. There was a message on that TV stating "YOUR TV DOES NOT SUPPORT THIS PROGRAM'S CONTENT PROTECTION, etc." So my 2 previous HDMI connections don't work suddenly with the new HR24. I had to steal the HDMI from my Apple TV to hook up my bedroom TV to get sound (and WH). Today, a technician is coming out. What the heck? Why with a different HR24 will my 2 previous HDMI's (already in place) not work? And there's nothing wrong with them because I checked them with other devices. Thoughts before the tech arrives today???
