Harvard makes some of their entry level classes available online.
David Malan’s Introduction to Computer Science is hosted at cs50.tv. They only show to most current published class, but Harvard been doing this for a few years now. You can probably find recordings of prior classes if you want watch them. A nice feature about Harvard’s OpenCourseWare videos are they shown a transcript of the class. Whats cool about these transcripts is that they support links. You can just click on transcript to where you want to watch the video, or if your a little savvy use ctrl F to quickly find your topic.
