 This is fixed, but I'm not terribly happy with the fix.

 The tuning process is just way to complicated, I'd like to break it up
 into states and handle it all in one thread. Right now it takes place in
 three different threads. The pause locking I implemented makes this
 but really it would be better to do the tuning in different states from
 within the RunTV loop, with multiple states that allow each portion of the
 tuning to be quick, but also don't require the 'abort' support or shutdown
 of the tune last from within Pause() when there isn't a signal, etc.

 If you changed the channel or exited the program you would just have to
 fallback to the untuned tuning state and then work your way back up to
 [re]starting the recorder. Now we have one tuning process before you start
 the recorder, another one after you start it (channel changes), and yet
 another process when you tune for the EITParser's passive EIT scan (where
 the recorder is not started).
