Ummmm... I give up. Things have just gone from bad to worse today. I've used both Camstudio and Windows Movie Maker before (separately) with no problems. Today, my video files are passing 100 Mb in about 18 seconds (not even recording full screen) and Windows Movie Maker refuses to open anything I record. If I do manage to get this worked out and get a video up, I'll link it back here.
Awesome videos! I would love to see this same principal in a steam engine. Have a normal small example of a steam engine boiling water to power it. Then remove the flame and replace the water with liquid nitrogen.
