Two classes I enjoyed and recommend without reservation. (I selected the audio classes. I think you can pick video if you want.)
Via Yale:
The Civil War and Reconstruction Era, 1845-1877, David Blight
(HIST 119) This course explores the causes, course, and consequences of the American Civil War, from the 1840s to 1877. The primary goal of the course is to understand the multiple meanings of a transforming event in American history. Those meanings may be defined in many ways: national, sectional, racial, constitutional, individual, social, intellectual, or moral. Four broad themes are closely examined: the crisis of union and disunion in an expanding republic; slavery, race, and emancipation as national problem, personal experience, and social process; the experience of modern, total war for individuals and society; and the political and social challenges of Reconstruction. This course was recorded in Spring 2008.

(CLCV 205) This is an introductory course in Greek history tracing the development of Greek civilization as manifested in political, intellectual, and creative achievements from the Bronze Age to the end of the classical period.
