I looked at the movie option for some reason, and realized that I'd done only half the job.
It now should record one side at a time of a PBEM or v. Elmer game. It will record both sides of a hot-seat or Elmer v Elmer game.
Oh, yes, I may be able to make it record AVIs with snapshots of each turn end, but that's more difficult. There's almost no documentation on how to do it.
