After putting Photoshow ver 6 on my PC then downloading the show, it came down as a .photoshow file not a .mp4 file. When I modify the show on the web and download from the web by hitting the Download a MP4, I do get a mp4 file but with only sound. The total size is 49 MG where I can load a previous show at 77 MG and it works fine. Any free utility to convert a .photoshow to a .mp4? Thanks!
