There are three main approaches to making videotapes from computer screen:

1) point a video camera at the screen.  Eye-boggling problems result, 
including roll-bars and flicker.

2) Television-standard ("NTSC") video boards in the computer.  May work well
for particular uses.  Problems include being tied to one computer, and software
may need to be video-aware. Vendors include:
   TrueVision, Inc.
   7351 Shoreland Station, Suite 100
   Indianapolis, IN 46256
   (317) 841-0332

3) Scan-convert the computer's own video output to NTSC standard.  This can 
be done by outboard boxes with quite good quality (considering the inherent 
limitations of NTSC).  A wide range of prices and features are available.

Naturally, I have no connection with any of these vendors, nor should this list
be considered complete.  It's just information I've come across in my work.
