Here is a link to some lectures on physics by Nobel Winner Richard Feynman. If the chunks are too long for you or you don't have the right video player Lubos Motl has some links to the whole thing segmented in shorter clips.
Feynman is very wise to do what I normally do. When he needs mathematics done he leaves it to mathematicians (which in some cases is Feynman himself). So to get these lectures may be conceptually difficult, however they will not be mathematically difficult. For those of you math challenged, no worries, mate.
