The last sentence in the paragraph throws down the
gauntlet:<br>
What we would like to see is this antenna attached to a
HTPC,<br>
and some kind of script to automatically direct the
antenna<br>
for the best possible signal for the current channel.<br>

<br>
I couldn't quite make out what they are doing here. Are
they a) moving the antenna to use different transmitters
for different channels, or b) moving it about to get the
best signal from a specific transmitter.<br>

This is for the former. You have stations in multiple
directions, and you want to record off all of them. This
cannot be done reliably without altering the code. You would
need the backend to support channel changing scripts for
digital tuners, to get the rotor in place before trying to
tune. You probably could do something with the system event
scripts, having mythbackend call a script on recording start,
but you're likely to run into timing issues.

This reminds me of something I thought about a long while back.
What about a "script" tuner type. I can't imagine it would be
that hard to create another tuner type that would simply allow you
to specify a script to run whenever that tuner was used. This
script tuner would be supplied with a variety of variables
whenever it was called, most importantly: target path, target
filename, channel, and end time or duration.<br>
<br>
Once mythtv kicks off the script it can either just ignore it and
assume its doing it's thing. Optionally the script could notify
mythtv of status changes (started, in progress, complete,
failed)... but it's really not necessary. The worst thing that
would happen is that the frontend would say that the recording
could not be found.<br>

<br>
That sounds like the import recorder.<br>
