Well with the Duo (Server) you have to do nothing no settings or anything else just keep the channels up to date
and if you have only 1 tuner configured you must set the Duo (Server) in standby when connecting the client
But if you have both tuner A and B setup you can watch TV on both without any problems
On the client you just install RemoteChannelStreamConverter and connect to the server with IP adress to the server (Servere ip address)
this you have done since you got it working allredy somewhat. Then download the Bouquet or bouquets to the client.
And now all should work just fine. You could if you use both tuners assign Tuner B as the preferd tuner for recording (Server Tuner B)
then you will have that tuner dedicated aslo for RemoteChannelStreamConverter.
You can not stream IPTV with this plugin only satellite/cable and terrestial channels.
The Client is a clone but should have nothing to say, but you can of cause try and install RemoteChannelStreamConverter again from the plugin feed
to see if that will fix your issues
