I have a problem where my HR54 will only have audio from networked DVRs. In my network I have one HR20-700, one HR24-500, one C61k-700 and the HR54-700. When I view recorded programs on the HR54, I can only view programs recorded on the HR54. When I try to play recordings recordedHR on either the HR20 or the HR24 on the set connected to the HR54, I get audio only and no video. I can view recorded programs on the set connected to C61K with no issues that are recorded on the HR24, HR20 or the HR54. I can view programs on the set connected to the HR20 that are recorded on the HR20, the HR24 or the HR54. I can view programs on the set connected to the HR24 that are recorded on the HR24, HR20 or the HR54. Obviously 4K only plays on the C61. I had tech support try to troubleshoot to no avail. On Saturday I had a technician onsite. He could not find the problem. He added a power unit for the swm, as the HR54 is furthest from the dish. The network is coax. He changed out the Decca. The C61 is the receiver hardwired to my router through the decca. I was able to previously watch programs recorded on the HR20 or the HR24 on the HR54. I do not know when this problem started. Any suggestions?
