You can find a lot of mfc videos at the following forums. Most of the time they get deleted pretty quickly so I only search back up to about 2 months but you can still find some active links further back sometimes.
You can also find them sometimes on motherless.com if you do a search for the webcam models name.
One other tip for finding these is to go to google and turn the search filter to "no filtering" and then do a search for the models screen name. Then click images and you will see screen grabs from the cam shows. That usually takes you to a forum with the videos.
Hope this helps. Let me know if you have any questions.
