Of course it does.  It just only works for channels that exist as a 
single number, such as analog cable, or digital cable when used with a 
virtual channel table.  You're trying to access ATSC channels, which 
means a physical channel and a stream ID.  MythTV is not able to pull 
both of these values, along with the handful of other necessary 
settings, from Schedules Direct at this time.

If you cannot pick up the channel in a scan, then you're not going to be 
able to pick it up to record from either.  This isn't like analog 
television, where you can watch a fuzzy signal.  Digital television 
includes redundant data, so the stream can be recovered completely and 
perfectly up to a certain percentage loss, after which you very rapidly 
drop to nothing.  If there's no potential to record the channel, there's 
no reason to insert it into the database during a scan either, so 
there's no harm done.  Get a better antenna or a more sensitive tuner card.
