OK, let's just leave it at this:
MythTV was designed under the assumption that it would have exclusive
access to all tuners in use and any non-MythTV usage of tuners will make
scheduling less-than-perfect, no matter what approach is used.
This means that whether you lock tuners, as suggested, or "steal" a
tuner from MythTV when you start up Live TV (and tell MythTV to allow
you to keep watching Live TV instead of recording the show it wants to
record), the result is the same--MythTV can't record the show it planned
to record, so it will try again, later, if it re-runs.
If, instead, you pull data out of the database (or out of the raw
Schedules Direct XML) and have mythfilldatabase load that data, MythTV
can't record the shows that were removed from the schedule, so it will
try again, later, if they re-run in a time slot whose data isn't removed.
Note, also, that if you delete data from the database or the raw
Schedules Direct XML, it will affect mythfilldatabase's decision about
whether to download data for that day (as it will see a
larger-than-it-should-see percentage of No Data for the day).
Therefore, if you do remove data, make sure you use the same approach
that mythfilldatabase --dd-grab-all does (so, if editing the DB
directly, use --dd-grab-all and if editing the raw data, download /all/
Schedules Direct data in a single request using the appropriate
tv_grab_na_dd arguments, and load it all at once using mythfilldatabase
--dd-file).
