With basic Blender animation, you create keyframes at different frames in your animation, and then Blender's IPO system fills in the blanks (the technical term is "interpolates") values for the frames in between. Sometimes you might want to base a particular part of the animation of one object, such as its location, rotation, or size, on the action of another object. This is where IPO drivers come into play. For even more sophisticated control, you can create a Python expression to do some really wild things. The purpose of this video is to introduce you to both IPO drivers and Python drivers (aka PyDrivers) so that you can really spice up your animations.

I guess IPO in Blender is roughly the equivalent to a "motion tween" in flash animation.

[irakrakow]

I'm not familiar with motion tween. The idea is that if you have to specify location (or anything else) for each frame, which is what animators did before CG, this would be a lot of work. Let you just insert a keyframe at important frames and let the computer figure out what goes in between. That's why a walk cycle can be done with 4 or 5 keyframes, with excellent results.
