Welcome to our community, Smileruner
This sounds like you have used Captivate and enabled the
"Full motion" recording option. Try using it differently. Use
Demonstration recording and you will still end up with many
different slides, but fewer actual files to distribute when you are
finished.
There are also issues you are probably unaware of with using
the Full Motion recording. If you create a recording that is long
enough, you end up seeing the "Red Screen Of Death" as playback
exhausts all available memory. Also keep in mind that it's quite
literally WYSIWYG. You cannot change aspects of Full Motion
recording after you are finished as you can with the other modes.
