I came across this article in my Twitter stream. It seems to be intended for those in North America who want to use TVHeadend with TBS satellite tuner cards, and one or more C or Ku band dishes. The author does not seem to care for OpenELEC or LibreELEC, and instead suggests installing Ubuntu Server or regular Ubuntu.
It would have been great to have something like this when I set up my backend system, so I am just passing it along in case it might help someone.
