I went the route of using
video screen capture software. I tried a number of trial versions from different vendors and finally settled on
WM Capture from
WM Recorder. I have only used it once to date, but it captured the Redlasso video very well (high quality, high frame rate) and it did a very good job on the audio as well. The other products I tried lacked video quality and/or did not record internal audio. For some products, when they say they record audio, what they mean is from a mike input.
