Maintaining forks are hard :-)

Wow! diff sounds huge!

Works for me. I also have a couple of scripts here to help updating from 
https://www.lyngsat.com/ and from a Brazilian site for ISDB-T. 

I'm run them right now to update dvb-s and isdb-t channels. With that,
it probably won't make sense for you to update dvb-s/s2 and isdb-t channels
from tvheadend fork.

Still, we have gaps on dvb-c/t/t2 and atsc.

Makes sense. Once we get this in sync, we can discuss further about how to
keep it updated.

Per-country-code seems good to me, but the sync has to happen on both
directions, as we've been receiving channels upstream too. Checking what
is the more updated version can be harsh, as you'll need to check it patch
per patch.

Merged, thanks!
