It's actually less the scheduler and more the source data. He won't be
able to use the same source for each tuner as all the guide data is
stored per source. If he removes it for one tuner, he removes it for
all tuners.

That said, he can muck around with duplicating guide data and thus
increasing the time it takes to run a fill database and increase the
scheduler time by a ton.

Also, if the mythfilldatabase runs during the window, all his guide
data will be added and myth will fight to get the tuner back until he
re-wipes the data and forces a global reschedule, thus losing
recordings and messing up the misses live tv viewing.

So yes, removing the data is a solution, but it has a pile of
tradeoffs not fully explored previously in this thread and is why
we're not recommending he undertake that solution. It's really not as
easy and error free as you guys think when dealing with multiple
tuners.
