hdhomerun HDHR-EU is it working with plex?

Hey im considering to buy a older model of the hdhomerun but i read a few discussions about that the older versions of HDHomerun is not working? Can anyone confirm that the “hdhomerun HDHR-EU” is working fine?

This says ‘all models’ are supported:

Make sure you have the latest firmware on your hdhomerun.

it doesn’t work for me. I have the hdhomerun dual hdhr-eu but I can only select DVBT while I need DVBC. The HDHomeRun windows application and config is running fine. Only Plex does not give me the option to scan channels on DVBC. (only DVBT). Any help/tweak/fix please.

Sorry, I am myself not experienced with this particular model.
