A misspelling? I doubt it. The name Xvid (at first XviD) for the opensource codec was chosen quite deliberately and it is not accidentally DivX spelled backwards. I can imagine some letters being switched by accident when typing fast, but not an entire word in the exact reversed order.

The version you're using (2.14
(unless exactly thàt's a typo and you're really referring to the recent beta version 2.41)) is from January 2007. Now I do remember that there have been some bugfixes with playlist in the past, but I cannot recall any bugreports similar to yours. I'm afraid probably no one of us still has version 2.14 installed, so that we are unable to try to reproduce your problem. Therefore I would also suggest you to update.
