Spent today trying to figure out a freeware solution to record a windows demo with audio commentary so that I can record some brain dumps for work. Ended up using camstudio.org but I had to drop the frame rate some to get it to work for any respectable length. But I have recorded a couple of them at this point and have a decent process.
This was a bit frustrating at first but quite gratifying as I have worked to remove barriers. Now, I love it. I have a way to pass along knowledge that is more durable than a good-luck-remembering-it walkthru and it is not as tedious to create as a document.
