I've been using Camtasia to make Mathematica screencast videos with an 
inset of my talking head. I save them directly out of Camtasia as MP4, 
post them on my department website, and link to them with a direct URL 
(rather than embedding them in a webpage). My students don't have any 
problems playing them on Windows or Mac.
