 the current implementation does not allow for dynamic tuner allocation,
 then adding locking won't impact that limitation. It only enforces
 MythTV's use of a tuner while it is using it.

 > I think you misunderstand.  You '''will''' lose recordings if another
 app already has the tuner in use (with a lock).  So in some scenarios you
 might win, but in others you have not improved your reliability (and that
 does not even include the scheduling challenges when the number of tuners
 changes at the time of the attempted recording).

 Right now:

 - Other app has tuner lock, MythTV loses. Recording failure
 - MythTV is using a tuner, other app takes tuner. Recording failure (even
 if available tuners are not in use).

 With patch:

 - Other app has tuner lock, MythTV loses. Recording failure.
 - MythTV is using a tuner, other app cannot take tuner. Recording
 succeeds.

 I understand that it will not fix all the problems, but it reduces the
 incidence of failure.
