Tvheadend

Satellite broadcasting is a big unknown to me. I'm used to just using a satellite STB and setting it up by running a scan and it generally works without me needing to delve any deeper in what is going on... TVheadend, on the other hand is far more complicated, but I feel I need to know a bit more about satellite broadcasting to get the most out of the program, so, rather than generating too much noise on this forum asking non-TVheadend related questions, can someone suggest another forum for asking more general satellite questions?
