I managed to receive RIK-HD with the following way:
- Disconnect the Cablenet cable from your TV
- Connect it to the old aerial antenna
- Perform a DIGITAL channel search on your TV (you should be able to find RIK-HD amongst other digital channels)
- Save the channels and reconnect the CableNet cable
You should now be able to watch RIK-HD from the saved Digital channels.
It worked for me. I have a SONY Bravia KDL-32W4000.
