    CS4 says missing or unavail codec when trying to open .avi file in abobe workbook cd


      I am running CS4 on a Mac and when I try to open a lesson from the Adobe lessons (In a Book series) I am getting a message that the codec is missing or unavailable for the AVI file.  Actually, it cannot find the file initially, and when I point it to it in the lessons directory I get the message when it trys to open.  Help
