Yes, your understanding is correct.

I did consider this briefly, but was more interested in getting the basic foundation in place.  As you say, though, it might make sense to differentiate this later (although the "typical" approach of trying to schedule a recording and then dealing with any conflicts is another approach to this).

Good question: I was assuming that DVB-S2 implied support for DVB-S as well (and the same for T2 and C2).  Supporting multiple source types is also a possibility, though: I don't think it would affect the overall shape of the API very much.
