I'm new to TVHeadEnd, and have just installed v4.3.0 on Ubuntu 25.04. I want to use it with my HDHomeRun, so have installed the HDHomeRun drivers. The tuner was detected, and an EPG downloaded, but when I try to "Watch TV" from a web browser I get "an unknown error has occurred".
I guess that I haven't properly configured my HDHomeRun in TVHeadEnd - is there an up-to-date guide for doing this anywhere?
