Ken, I have now installed the codecs in the appropriate folder and they now appear in the Pte custom create dropdown menu. Unfortunately,for me, there was no file marked, "install" , in the zipped file which I downloaded.It was marked set up information it simply needed a left click of the mouse and not a right click which showed merely the contents. I visited www. free- codecs. com web site several times for the install instructions. Don't worry Ken I was only using my desktop as a temporary measure for the zipped file.Many ,many thanks for your help. Finally, what is mostly used to place a PTE slide show on a web site, a executable file or a video file? Ted.
