In response to a question asked by alanstanscliff in this thread, here is a brief discription of how I made my videos.

I used Designer Pro 7 for the graphics and demos, and Fastone Capture for the screen recording, and in the most recent few videos I put together a presentation using designer pro 7 and made a screen recording of that in full screen preview, as I used the keyboard arrows to navigate through it and recorded audio as I did that, I made a second screen capture of the actual demo in DP7 and used videoPad to combine the clips and edit out a few pauses here and there.
