I've tried everything I can think of and this HDX 9004 unit will simply not send camera and content at the same time. Camera sources are set as 1 is set as Main, 2 is People, 3 is set as People, 4 is set as Content, 5 is set as Content. I'm able to send the camera feeds fine by themselves fine for 1 and 2. When I try to send Content it shows on the far side but the Camera feed disappears. I have an identical system set up with the same settings and it works fine. I've also tried another network to rule out that and it still didn't work. I tried toggling through the display modes and changing all the people/content settings but it still doesn't work. Any ideas?
