What I tried was to activate the “TvHeadend Client” from the addons-section and configure it with the credential provided in the TvHeadend server page. I get a popup on boot saying the TvHeadend is connected.
If this is the proper way to set thing up, I think it should be added to the wiki (and if this is not, I guess I messed it up again).
Anyhow, when a go to the TV/Recording menu i get a page that is empty with no loading screen. And wen pressing the left button on the remote I get a sad face then a tty1 prompt.
Of course, it all depends on what the other end of the Coax cable is connected to…if anything.
If your building has a rooftop antenna system (MATV) for off-air channels, and the coax is connected to that distribution system, you should get some channels.
However, if the coax cable is for a cable TV system, first it would have to be connected to that system on the other end, and second those channels may be digital and/or encrypted.
Here in North America, almost all cableTV systems are completely digital and encrypted and IPTV. You cannot get any channels without a set-top-box (STB) from the cable company.
