Ideally Sky NZ could have supplied detailed hardware specs to Samsung NZ so they could work on why the new decoder did not work with the TV - what the decoder does (or does not do) is key. The Service Agent had some limited test-and-repair capability but it could never address the issue unless he could 'interrogate' the decoder to find out what Sky have not provided.
What other types of devices will work with the TV is not particularly relevant.
