Hi I also receive the same info: "Service not supported". Don't know what they did to the hardware but there was some changes. Here is link to reddit topic, Would be good to ask what is the reason that we don't have image:
This is strange because on LG I get this message as mentioned but on Samsung TV I have only sound. At least I'm not the only one with the same issue Found some info that it's now broadcasting at 60 fps and that might be the issue. Previously it was on 30 fps.
