I agree with you Craig, a short video can act just like a commercial for your product. People are much more likely to watch an entertaining video over reading your sales copy. And if they like the video they may just put in the extra time to read the sales copy too.

Video does suck up a lot of bandwidth, one way to avoid that is to use YouTube, Google Video, or Revver, but you have to not mind the sites branding on the video.

I didn’t want to have the branding so I purchased FLV Producer and am very pleased with the purchase, but I have to support the extra bandwidth the video sucks up.

If your site doesn’t have a lot of bandwidth you can also always iframe the video with another site you have which might have some extra bandwidth. That way the extra resources the video requires will be charged to that other site.
