Recently I used the AverVision software that comes with the AverMedia Document Camera CP300 to record a video demonstrating the buttons of the Flip Mino Video Camera. I used Windows Movie Maker to edit the avi file that was created by the AverVision software. The sound quality is a bit lacking, but overall not bad for a first attempt. (I think the microphone on my headset was too close to my mouth.)
