I burned 2 slideshows onto a DVD.  The icon to launch the second file will not show up on my screen nor can I find a menu command on my DVD player to make it appear. Nero Showtime says that I do not have a valid DVD Video, S-VCD, or VCD Structure and it will not display either Icon. I can run either slideshow from my DVD drive in Windows Explorer by clicking on the appropriate file name. I tried creating que files but I cannot manage to burn both of them onto the same disk be
