Extra Credits once did an absalutly awesome series on the Punic wars:
While not videos, if you listen to music or podcasts on the way to work or classes, Radiolab will just blow your mind each and every time. Very high quality podcast meant to show science to the general public in a non talk down way while still retaining a good density of information. Blisswas their best one imho, speed is way up there, and one of my favorites, the Million Dollar MicroSecond.
