Yes.  The RF input is hooked up to an 11ft Winegard roof antenna, mounted on
a stand behind me, properly oriented according to antennaweb.com for the
local stations, and with a UHF pre-amp for good measure.  It is inside, but
a foot below the reasonably high ceiling, so it doesn't interfere with moving
around.  With this setup I have succeeded in receiving barely visible
analog channels when the Creator is set up as a v4l device using /dev/video0.
Yes, the reception sucks, but I want to make sure that it is not something
more fundamental before I go to the trouble of mounting the antenna on the
roof.

Right now, the unit is set up (in mythtv) as a DVB DTV receiver.  I have
observed that the red led seems to be on when configured in digital mode,
as it is right now.

I'm not sure how to change the cable vs. ota setting.  Doesn't the digital
tuner determine what it is plugged into?  As far as mythtv, it thinks the
attached device is a DVB/DTV receiver.  Kaffeine has been told to use the
us ATSC frequencies, with the results I pointed out earlier.
