[mythtv-users] Padding on Same Channel But Different Tuners

Yes, that's the request in the database. And yes, I'd also assume this was more difficult than a scheduling change.  But I like the solution better.  The extra advantage is that if all your tuners were busy, each could still have padding on back-to-back shows on the same channel.

But that feature isn't probably going to be implemented soon.

So on that note, is the scheduling done in a modular enough way that it could be replaced?  I mean if I were gutsy enough to think I could create an algorithm that would cover all the corner cases, would it be possible for me to use my own instead?

Why not allow (and even prefer) back to back recordings of the same
channel using the same tuner and just write the stream to both files
during the overlap period.  This would be compatible with both hard and
soft padding and wouldn't require the presence of a spare tuner? The
only issue that I see is that this is probably more complex to implement
than the scheduler change to either force the use of a second tuner or
for one of the programs to be rescheduled for a later time.
