Digital TV is just a CF all around.  Part of the problem is the cable
companies, which don't want or care about interoperability. It surprises
me, though, that no one has come up with a good solution for OTA yet.  Am
I right in thinking that it still requires filling out channel IDs by hand
to get it working with Schedules Direct?

I suspect part of the issue is that the whole concept of a channel number
has become very abstract in the digital TV era, since they're no longer
tied to specific frequencies.  TMS (and by extension, Schedules Direct)
started out in the analog era and probably still revolves heavily around
channel numbers as unique identifiers.

A common problem with open-source software.  Open source software only
solves problems that someone finds fun to work on.  Writing documentation
isn't fun.  Worse, programmers usually particularly hate writing
documentation, and they're the only ones who know how the thing works. 
This is a long way of saying that this is a long-standing complaint and I
doubt it will  be fixed any time soon.

The de facto solution seems to be to rely on the mailing list as a sort of
living source of documentation.  Ironically, this is way more
labor-intensive than writing actual documentation would be...

I think the official position is that end users shouldn't be messing
directly with the database, anyway, so I doubt documenting it is high on
the priority list.

That seems like the kind of thing that ought to be tested for in the code;
it sounds like an easy, basic sanity check.
