Ken, I did this on my XP machine and used Snagit 10 for the capture. I've been testing Captiva on my Win 7 machine. It'll do higher res video and has a video editor built in. Snagit has done a decent job, though. I tried a number of freeware and very low cost screen capture apps but they had problems keeping video and audio synchronized.
I think I'll have to find my own "that" for the next Basecamp. That's a great idea.
