Play next no longer interrupts the episode. (#34)
The card had two rules and the second one cancelled the first. The top rule reads the credits marker and approves it; the bottom rule opens the card 120 seconds before the end, unconditionally. On every episode whose credits start less than two minutes from the end — which is most of them — the blanket rule got there first and the card came up while the episode was still playing. The marker that exists precisely to prevent that was being read, approved, and then ignored.
Movies got this same guard in 1.0.35. Series were left out of that fix.
Now an accepted marker decides alone: the card opens when the credits actually start, and not before. A marker that fails the sanity check (credits somewhere in the middle of the episode — bad data) still falls back to the two-minute rule, otherwise the card would never appear on that episode at all.
Also in: the card now reads the Matroska credits chapter too, not just TheIntroDB. The chapter was already being obeyed on the movie panel and ignored here — two different readings of the same file.
