   Something like that, indeed. I was going to start with DVB-T rather
than DVB-S2, since that's what I've got, but that's a trivial change.

   I don't (yet) understand what erlang drivers actually do. Looks
like I've got some reading to do this evening.

   So I can read from it in erlang without proxying the reads through
some other language -- if I didn't need to configure the tuner, I
could just open the device and read data from it, so that felt like a
good approach. After that, the problem reduces to working out how to
do the tuning... which then led to my original question.

   Hugo.
