Video and ISBN

we recently started using Telleco to manage our book collection went 
through almost 1000 paperbacks alone in a week. what we would like to do 
next is our video collection. I tried to set up the forms up in the 
video collection form to do a ISBN (since most recent videos have a ISBN 
number). but I could not make it go. not really a programer anymore. (20 
years out of touch).

has anyone done this or have a quick and dirty patch/fix for this?
