Hi Niels.. Welcome
Does the gemist plugin work ok when you control it with the arrows on your keyboard and "esc" to go back ? (this is basicly what your remote should do)
You also have to be aware, that shows with a lot of daily broadcasts will take some time to load the program list (like journaal / Nova)
Also make sure you got the right codecs https://forum.team-mediaportal.com/...-55/standalone-filters-mediaportal-saf-44614/
Hope it helps you out any....
