I am brand new to DSG, and am creating my first slideshow. I have a couple of AVI videos in addition to my jpg images. When I play the slideshow, either in preview mode or after exporting to mp4, the AVI videos play in slow motion. This isn't really a problem for silent AVIs, but one AVI has a person talking, and, of course, it sounds like it's in slow motion. I see no settings that control playback speed. Has anyone else seen this? Is there something I can do?
