Quoting tracy at amphibious.org:

I added "Full Scan" for ATSC about 2-3 weeks ago, so you can just do a "full
scan" for ATSC/Digital Cable (I need to make it try both QAM64 and 256 though),
and you don't have to manually add anything.. I had thought about adding to the
frequencies table myself.. The ATSC channels are probbably OK, but the QAM ones
I am not sure if they have to follow cable channel frequencies.. (I have no docs
that confirm nor deny this)..
