Steve,

If no one comes up with a simple fix, you might try this.

Get Graphic Converter from,

http://www.lemkesoft.com/

Open movie with GC, then go to the file menu and select "Save a copy  
as". In the save window, select "pict", "Jpeg", or whatever as the  
format, make a new folder for the saved files, then click "Save". At  
this point you'll get a new window that will let you select "Export  
all available frames". Once you've selected this, click OK. All the  
frames will be saved as individual images in the format you selected.  
These can then be re-assembled as a movie with GC, Quicktime Pro, or  
some other such program.

Hope that helps,

Steve
  PS If GC won't open your Quicktime movies, there probably is a  
problem with them.
