they can record to tape and output to A/V at the same time. DVD cameras are junk. John

I need to chose a video device for our educational project that we can use simultaneously as a web-cam with a modest resolution for internet (skype, ichat, etc.) video conference courses around the world as well as to record that class at a higher resolution, though high definition is not needed. Recording directly to DVD appeals to me because of the cost efficiency and ease of duplication. We will have to purchase quite a few of these, so cost is an issue.
Any thoughts, recommendations, etc?
