I have thought of other forms--even made some outlines for some video tutorials. Unfortunately they take more time than I have.
Also, I test drove Cam Studio several times and looked at some other realtime screen capture software but since I am running an XP (from about 10 years ago) with about 1.37 GB of RAM, the results were not good.
I suppose I could do the audio only thing in realtime, edit that down, and then re-create static screen shots to lay on top of the edited audio track.
