Same thing here Erich. I tried connecting magic LG Remote to my set-top-box, and I notice that for some devices in the Device Connector list, the menu in the upper right corner goes to done right away and for some devices it goes to Simplink first as you explain and then to done again. I never get the chance to reach a menu out of which to choose my T-Home set-top-box, from a list of manufacturers, or furthermore try and test the working optional remotes, as they explain on the tutorials.
Did you by any chance found a solution to this, since I try resolve it as of yesterday, and cannot find any other thread on this topic on the web. The restart, power off and back on, as well as disconnecting and reconnecting devices did not do the trick too.
