[mythtv] LiveTV bug

[Joseph A. Caputo]

If the front end is killed (i.e., via a signal) while watching LiveTV,
then when the front end is restarted it won't allow you to watch LiveTV
again because "all inputs are being used for recording".  There is no
in-progress recording in the list to delete, since it was LiveTV, so the
only option is to kill the backend and restart.

This is with a recent CVS.

BTW, what ever happened to the old method of asking if you would like to
cancel the in-progress recording, rather than making you go to the
"Delete Recordings" screen to stop it there?  It seems that would
present a good workaround to this issue.
