With a little help from Bill Gates (who secured the rights using personal funds), Microsoft is presenting a series of lectures on physics by Richard Feynman. The lectures, shown in seven hour-long segments, were recorded by the BBC at Cornell University in 1964. Lecture titles are as follows:

Law of Gravitation - An Example of Physical Law

The Relation of Mathematics and Physics

The Great Conservation Principles

Symmetry in Physical Law

The Distinction of Past and Future

Probability and Uncertainty - The Quantum Mechanical View of Nature

Seeking New Laws
