Higher Level Math Video Resources

Hello! I'm completely new to this forum and hope someone here can possibly point me in the right direction.
Currently i am taking calc3 (series, sequences...etc). So far throughout my calc classes i've been supplementing what the teacher have provided with various math videos. I've been mainly getting my videos from hotmath.com... but i am about done with the highest level of math videos they provide. After calc3 i'll be going to calc4 then differential equations and so on, and i'd highly appreciate having some videos in a single place that i could rely on to clarify something i may have missed. That and i learn quite a bit easier with video material.
Does anyone here know of a particular resource where such videos exist?
Thanks

Youtube is a good place to start...

Thanks... but the idea is for a collection of videos, or a video series, that are cohesive and follow some sort of order. I'm already aware of youtube, and have used it for math at times, but it's not quite what i'm looking for.

The following site contains many free video lectures in mathematics:

Khan Academy

My Website Calculus7.com in the ad on this page contains a large number of animations for Calc3 and differential equations.

However there is a $30 subscription fee

Thanks guys, both of those work. In particular seouldavid, your suggestion is exactly what i'm looking for.

I second Khan Academy. If your Calc 3 involves sequences and series (and methods of integration, etc.) then thats equivalent to Calc 2 here, and Khan definitely covers what you should expect in your next semester (partial derivatives, vectors, etc.) Plus the guy has a real relaxed way of talking, is pretty humorous (even when he's not trying to be) and when he makes mistakes (not often) he catches it.
