While I was reading a PC mag I came across an article from a Helen Bradley that covers Windows Media Encoder and according to Helen:
Windows Media Encoder can capture the screen as you perform a task such as editing a photo; in fact almost anything you can do on the screen can be recorded as a video.
It’s a good article… I’ll have to go look at it and see if it will work for when I have to help people and want to show them “how to do this or that” on the computer. I wonder if I can find something that’ll take the AVI (I’m sure since this is Windows that it’ll be in AVI format) into something more generic… (Also, she included this link for more info.)
