[mythtv-users] is mythtv smart enough to do this(overlap/back-to-back) with recordings?

You responded to a response to a post of mine with that link. Neither
Steve Daniels or I were talking about a single recording containing
data from two tuners. It's not that I don't understand what you were
going on about, it's that I don't see the relevance.

Who is suggesting it should be? If two adjacent programs are being
recorded on two different tuners then everything's fine. What's your
point exactly?

Again, that's not the implementation most people here are talking
about. We are talking about a single tuner writing two adjacent
recordings to two files and including the overlap in both files.
