s/edit the database manually/delete and re-create the video source
(including rescanning)/

Can't answer the why.  Daniel K. may know more.  It was changed
http://svn.mythtv.org/trac/changeset/15776 such that we can't
accidentally forget a valid format in the settings (leading me to
believe that ATSC is no longer a valid choice for a user to specify).
