Panasonic DMR-BS850EBK when I connect to my Phillips 55OLED936/12 Video format not supported appears on the tv codes U73 F5 flash up on the recorder. If I disconnect it from everything and try again in a few weeks I can play a BD disc or something from HD. Then it stops working again.The twin tuners stopped working years ago. Disconnected the satellite leads and then reconnected again and tuners never ever worked again. Hope this makes sense.
