YouTube can certainly be an embarrassment of riches. Just last night I found these two re-enactments of the Seder shel Pesach: one Sefaradi, and one Temani (Yemenite). For the Sefaradi seder, click here. For the Temani seder, click here. Please note that these are re-enactments, as direct operation of electrical equipment is forbidden on yom tov. I'm sure there's much more available for viewing, but this should hold all interested FReepers for now. Wishing all a Pesach kasher vesameach!
