I’ve just released a great new Actionscript video tutorial (by our resident Flash-nerd Santo Romano) that covers a couple of things:
The differences between Actionscript 1, 2 and 3.
How to bind Actionscript to a button.
Though (in this video) you learn about binding Actionscript to buttons, the main goal is to show you the differences between the different versions of Actionscript (using a simple to understand button example) while showing the advantages of Actionscript 3.0.
Check it out:

I hope you find it useful.
