If I may also suggest
The Teaching Company

The Teaching Company brings engaging professors into your home or car through courses on DVD, audio CD, and other formats. Since 1990, great teachers from the Ivy League, Stanford, Georgetown, and other leading colleges and universities have crafted over 250 courses for lifelong learners like you. It’s the adventure of learning without the homework or exams.
I'll second that. I'm a major fan of the Teaching Company. Outstanding lecturers and courses and they're constantly adding more. They've provided the education I didn't get in college.
