And as Bruce was trying to make clear after my post (which didn't make
it clear), it's actually the input connections that must be in order
(i.e. "then configure the input connections" should be "then configure
the input connections in the proper order"). Or, as he described, add a
card and connect its input then add another card and connect its input...

He's positive. He wrote much of this code.

Yep. Which is part of the reason why "Delete all capture cards" (and
"Delete all video sources") happens to be special. That's also why some
posts (i.e. ones I often write) tend to make such a big deal out of the
whole "Delete all" thing.

Potentially--assuming the cardinputid changes. But, considering the
user is setting things up correctly this time, it's unlikely to ever be
redone again. And if it is redone (i.e. the user adds a new lower
quality capture card or removes some capture cards or whatever), the
user will need to tell Myth what's changed, anyway, so the user will
have to reconfigure priorities. But then again, both Bruce and I are
recommending that the OP fix the issue described without priorities.

There is one (technically for card inputs, which are the things that
must be in order, anyway), but it affects the recording, not just the
card, which is why the non-/recording/-priority approach--putting best
card input first--is more appropriate.
