Using Photostory 2020, I created a slideshow with about 400 photos and ten songs. When I burned it to DVD, all worked fine. When I exported to a file on my PC, two songs did not burn. No error message, the music was simply not in the show. I purchased all music from iomoio.com, .mp3 format, which I have been using for ten years without this issue.
Any advice would be appreciated.
