Worse, the smart apps may pull a tuner out from under the
use of MythTV.  Currently MythTV natively does not implement
shared/pooled/locking of the available HDHR tuners (that was
the purpose of the aforementioned external recorder).  Of
course, the future is hard to predict (nor when it might
arrive).

The MythTV architecture, today, has a lot of presumptions
about knowing what tuners are available to it exclusively.
Not only do recordings (typically) fail if the tuner is
unavailable (depending on exact specifications,
sometimes it will be recording anyway), the presumptions
go all the way down to scheduling (if it could know, 24
hours in advance, that the dog was going to be watching
Animal Planet on live TV in its dogPad in the crate it might
schedule the (now) smaller number of available tuners at that
time in a different way to not record some lower priority
program (for the cat, obviously)).  Arguably if the project
was able to provide native apps for the smart TVs, the
iDevices, the ATV boxes, etc. then MythTV could again
become the center of everything, but the resources do
not seem to be available to implement and support that
diverse ecosystem, so some (better) sharing is needed
for those tuners to avoid the cats and dogs arguing over
who gets to control the world.
